Clarifying a few things

Hello,
I'm soon to start university and i need to purchase a laptop. I also like to play World of warcraft and i also need Wi-Fi on my comp.
I was thinking of buying the following comp:
MacBook 2.0GHz Intel Core 2 Duo - Black
- 2.0GHz Intel Core 2 Duo
- 120GB Serial ATA drive @ 5400 rpm
- Apple Mini-DVI to VGA Adapter
- Apple Mini-DVI to Video Adapter
- Keyboard/Mac OS - U.S. English
- Accessory kit
- 2GB 667 DDR2 SDRAM - 2x1GB
- Superdrive 6x (DVD+R DL/DVD±RW/CD-RW
I have the following questions:
1. Do i have to buy extra wireless internet cards of any sort? if so which ones?
1.5. if i have a normal network at home with extreme speed internet and just buy the express airport base and plug my internet wire in there will it give my laptop slower internet speed? Whether it slows it down or not will i even get internet?
2. What kind of Graphics card does it have does it play World of Warcraft properly?
3. how do i get Both Windows/MacOsX on my computer?
4. How long does the battery last, does it make it last less long if i keep it plugged in most of the time?
Thanks for your dedication and time
Can you also email me the answers? thank you

1.5. if i have a normal network at home with extreme
speed internet and just buy the express airport base
and plug my internet wire in there will it give my
laptop slower internet speed? Whether it slows it
down or not will i even get internet?
I guess you mean ''AirPort Express Base Station'' ? It has 10/100BASE-T Ethernet
so,unless you have more than 100 Mb/s Internet speed,which I'm doubtful
about,it won't slow down. Otherwise you'll be fine.
4. How long does the battery last, does it make it
last less long if i keep it plugged in most of the
time?

Just looking to clarify a few things I read here

I currently have a 5508 WLC ver 6.0.202.0. My WCS is at version 6.0.132.0, I am using 1142's, 1131's and 1231's. At the current software levels, are there any other access point models that would be supported? I am looking particularly at 3500 and 3600's. If they are not supported at current levels, what should be the minimum software version for the WLC and the WCS?
Thanks,
Gene

Gene,
The 3600's will require the 7.2 code and that is only supported on the 2504, 5508, and WiSM2. Your WCS version should also be equal or a higher version than the WLC firmware.
The 3502 requires a minimum of the 7.0.98.0 wlc

My iphone 4s will not allow me to open any apps that I have downloaded. I have tried a few things but still will not allow me to open. Shows they are open once pushing the home button twice. Please help!

My iphone 4s will not allow me to open applcations that I have downloaded. I have tried a few things but still will not allow me to open. Shows they are open once pushing the home button twice. Please help!

Pressing the Home button twice does not show you what apps are running. It shows you what apps were recently used.
Download a free app from the App Store. Once it downloads, your other apps should work properly again.

Can I use Leopard Server for a few things without a static IP/DNS mapping?

Caveat: I'm pretty capable at setting up and running macs, but not a crack server admin or anything like that. I don't write code and my eyes start to glaze over when you start talking about Kerbos and the like...
Question: I'd like to use Leopard server for a few things on my local network - with some vpn access to the same services:
- iCal server (the most important feature) for 3 users
- File server services for Time Machine (yes, base Leopard can do this)
- vpn access into the iCal server for one user
Do I have to go through the headache of switching over from a dynamic IP to a static IP, setting up DNS mapping, etc? Or is there a simpler way?
Any help appreciated. Thanks

HT1296 i have a load of stuff on my ipad but I can't get it onto my conputer, pressing sync comes up with a message saying it will all be deleted. I've transferred all purchases but this only does the few things I've got from apple (apps and a few itunes)

I own an ipad2 and have loads of music and vids/photos etc on it from an old pc.
I just bought a new pc and wanted to transfer everything to the new pc
I've transferred purchases but this only transfers things bought in the itunes store like apps and a few songs
The rest of the content is still on my ipad.
When I press sync, it warns that it will delete all the content on my ipad and replace with the few things I've managed to import.
How do I transfer all the content to the new pc?

I am already fedup with asking questions..begging for an solution.....
I hope so you can help to figure it out, without any complications....thank u!

It was not legitimately unlocked by the carrier it was originally locked to. ONLY the carrier it is locked to can authorize unlocking it.
In order to allow it to be used on a different carrier, the phone was hacked or jailbroken. An unauthorized modification was made to the phone. That modification has damaged the phone. You can not get support for it here or from Apple.

How can I change the insert SWF File, I need to add a few things and make it better?

How can I change the insert SWF File, I need to add a few things and make it better? Is there an option inside of the dreamweaver menu that I am not looking at. It would make it easier on me if I changed some things around and didn't have to do it all myself each time I used it. Just incase you was needing to remember what swf flash was, It is not a swf video either.

If I understand correctly, Sonic Kaboom.swf needs to be edited in a separate Flash authoring program and then reinserted into your HTML document.
As Murray said, Flash is dead. Nobody uses it anymore.   We use HTML5, CSS3 and JavaScript animations which have universal support from Smartphones, Tablets and other web devices that can't support Flash.   Look at Edge Animate.

Would love to see a few things added... the ability to easily add noise and to have more font adaptability. I usually have to go to another app for this. Any chance of these being included in app?

Maybe you can buy two Lenovo products, one is the latest ThinkPad Compact Bluetooth or USB Keyboard with TrackPoint, another is a ThinkPad Numpad.

After upgraded to version 5 few things missing..

Hi,
I am using blackberry curve 8520.. I have been using this for almost a year already. I noticed, there are few things missing and some problems occurred when I upgraded to version 5. Eg. Memopad, No column in option for alarm tones, my BB getting slower during browsing, everytime I try to connect to wi-fi, it will be intermittent or not connected.
For unable to connect to wifi, I suspected it is browser issue but then I set to default setting it is still the same.
Can somebody help me to rectify this please?
Tq.
Solved!
Go to Solution.

Memopad: 1. On your homescreen, press the Menu key > SHOW ALL, so that SHOW ALL is checked.
2. Look in EACH folder on your device... Applications, Instant Messengers, Downloads, etc.
If you still don't see it, look at Options > Advanced > Applications. Do you see it listed there?
If still can't be found, read this link.
Alarms tones? Can you elaborate?
Slow or lagging device, please see below.
i don't know about your WiFi issue, you would also need to elaborate your problem.
To prevent freezing or lagging/slow response on any BlackBerry, the most important practice you can adopt is to be sure to CLOSE applications when you are finished using them.
If you just hit the red "end call" key to go back to the home screen the application actually stays open and running in the background. If you do this repeatedly you will have lots of apps open and consequently your memory will get used up. Lack of memory is the biggest reason your BlackBerry slows to a crawl or locks up. If you get into the habit of actually using the menu key to close the applications this will at least slow down this memory-clogging process. You still may have to do a battery pull or use the "Quickpull" app once in a while when things get slow.
To check what applications are running on your device in the background, press the Menu key then choose Switch Applications. You will see the icons of each application there.
So now, check your applications running in the background. There are commonly four or five applications that will always be running (Messages, Call Logs/Phone, BlackBerry Messenger, Homescreen, and the Browser; there are other third party applications such as BeeJive, and BlackBerry Alerts which will also run in the background which you cannot close if you want them to operate). Make certain that the browser is NOT on an active webpage (open the browser and choose Menu > Close). Close any other applications that do not need to be running (the camera or a game you were playing or Google Maps).

I think you need to do a crash course in JSP/Servlets, by the sounds of things you're about to embark on a whole heap of frustration if you use applets for this. Step one in any project, get the right tool for the right job

Few thing you need to do on the rotue & X-BOX ... Cha...

Few thing you need to do on the rotue & X-BOX ... Change the MTU size under setup page of the rotuer ..from 1500 to 1365 ... click save settings ... Uncheck block WAN request under security tab ... click save settings... Under Port forwarding use port numbers ... 88 & 3074 ..for static Ip of X-BOX ... On X-BOX you need to use static Ip ...subnet ..default gateway ... also you need to use DNS numbers ... Hope it helps ...

FYI-
If you delete the managed account and save the home folder, then create a new local account with the same name, it does not recognize that the home folder already existed so you end up with a brand new profile...(bummer) The only option is to move the users data to the new home directory. If you simply unbind the machine from the domain, the account still works but I am not sure of long term implications, so far, all I've noticed is that the user cannot change their password....

A few things that might help before updating to 4.0 (if you haven't yet):

I'm in the IT dept of the company I work for and it's my job to troubleshoot, test, implement etc etc everything and anything regarding iphones and other related software. So, after MUCH trial and error, here are some of the key points I have found regarding the upgrade that I hope will also help other people as they have myself and others whom I work with. So here are some snippets of the mass email I sent out to our other associates who have yet to upgrade their OSs:
In order to make sure that you're upgrade goes as smooth as possible: please take into consideration the following recommendations:
1. It is not necessary to do the software upgrade on the same machine that you normally use to sync your phone.
I sync my phone at home on a PC, but upgraded the software at work on a Mac. I lost no data/music/photos/contacts/applications and it was fast and easy. I highly, highly, HIGHLY recommend you do your firmware upgrading on a Mac. I also did it at home on the pc and it was a nightmare. I had to uninstall and reinstall every scrap of Apple software I ever had on there and all kinds of other permissions/backup problems ensued.
Do yourself a favor and DO NOT upgrade your iphone's OS on a PC.
If you do not have a Mac, chances are you know somebody who does who will let your borrow their iTunes for an hour.
2. Obviously, you will need the most recent version of iTunes (9.2) and OSX10.5 or later on your computer (OPTIMALLY, you will have 10.6.4). Again, do this on a Mac. If it is not, please download and install 10.6.4/9.2 (DO NOT have your phone plugged into the machine while you do this). Wait for everything to upgrade, then restart your computer.
3. Always, always, always make sure you have a reliable backup of your phone's contents SOMEWHERE (it doesn't necessarily need to be on the computer you use to sync it, and to be honest I would recommend NOT using that same machine for the firmware upgrade). In the off-chance that your upgrade fails, you will lose all of your data if you do not have a backup.
4. Once all of your machine's software has been updated, go ahead and open iTunes THEN plug your phone into your machine. Once it finds your phone, it will likely automatically prompt you to upgrade your phone's firmware and carrier settings. Accept this.
If it does not, please choose the "check for update" button on the summary screen of your selected iphone in itunes.
Downloading and installing should take roughly 20-45 minutes (depending on your speed/connection). Itunes will create a backup of your current data/settings before installing this which shouldn't take more than 15 minutes and will overwrite your previous one.
You should not encounter a need to sync ANYTHING at this point, so please please please do not sync before updating. Keep it plugged in and do not answer any incoming calls, texts or emails while this is occurring. In fact do NOT use your phone at all, in any way while the update is being downloaded or applied.
5. If all goes well, your phone will restart itself after the installation. This will take a few minutes. It will disappear from your itunes during this time, but fret not, it will return. When it does, and you are told by itunes that the upgrade is complete, it is now safe to disconnect your phone and try out all the new features. (A reboot is HIGHLY recommended)
All of the listed features of the new iOS4 will be fully operational on all 3GS phones. 3G phones will not be able to multitask, among a few other things but nothing about its basic functionality will be removed. This update is not available for 2g phones at all. Once updated, it cannot be retrofitted with the old firmware without hacking and if you hack your phone, I will not support it and neither will Apple. Also, the FaceTime video chatting function is only supported on the iPhone 4.
For a comprehensive list of all of the cool new things you can now do with your upgraded phone, I recommend you READ the following links:

Hi - my IT department directed me to this page as we have been experiencing a few sync issues etc. So I downloaded the patch - my email account will not sync properly now. Is there any way I can uninstall this patch?
iOS 4: Exchange Mail, Contacts, or Calendars may not sync after update
Last Modified: 28 June, 2010
Article: TS3398
Symptoms
Immediately after updating to iOS 4, some users may notice that Exchange ActiveSync Mail, Contacts, or Calendars do not sync, or sync very slowly. In addition, some Exchange Server administrators may notice their servers running slowly.
Products Affected
iPod touch, iPhone 3G, iPhone 4, iPhone 3GS
Resolution
To work around this issue, users should install a configuration profile from Apple that increases the amount of time the iOS 4 device will wait for the Exchange Server to respond to its sync requests. For best results, the profile should be installed on as many iOS 4 devices at your company as possible.
To install the profile:
Use Safari on your iOS 4 device to download the configuration profile. It may be easiest to read this article with your iPhone or iPod touch and tap the download link there, but you may also email the attachment to another email account on your iOS 4 device, and tap the attachment to open it.
Tap Install to install the profile, and enter your passcode if prompted.
A warning message will appear because the profile is not signed. Tap Install Now.
Tap Done to complete the installation, then power off your device and power it back on.
Wait for your Exchange data to finish syncing.
After installation, the profile will be listed under Settings > General > Profile.
