How Do I Get Rid Of The “Other” Data Stored On My iPad Or iPhone?
http://tinyurl.com/85w6xwn
With an iOS device, the “Other” space in iTunes is used to store things like documents, settings, caches, and a few other important items. If you sync lots of documents to apps like GoodReader, DropCopy, or anything else that reads external files, your storage use can skyrocket. With iOS 5, you can see exactly which applications are taking up the most space. Just head to Settings > General > Usage, and tap the button labeled Show All Apps. The storage section will show you the app and how much storage space it is taking up. Tap on the app name to get a description of the additional storage space being used by the app’s documents and data. You can remove the storage-hogging application and all of its data directly from this screen, or manually remove the data by opening the app. Some applications, especially those designed by Apple, will allow you to remove stored data by swiping from left to right on the item to reveal a Delete button.

What is javadoc for and how can i use it?

Hello,
I want to know what for
*/is and how I can use it?

It works like this:
You add comments between /** and */ in your source code for all your classes, methods, variables etc. Then you run the javadoc tool, which is included with the JDK. Read the Javadoc Tool Documentation for instructions about how to use it.
The javadoc tool looks at the comments in your source code and generates a directory containing HTML pages. The HTML pages contain the documentation of all your classes and methods.
Why would you want this? Because other people who are going to use your source code do not want to browse through all of your source code all the time to find out how your classes work. Having a good manual in the form of HTML pages generated by javadoc is much more convenient.

Events: what do they mean and how can I use them?

Hi everybody,
I'm new to this, so it's maybe a silly question. I can't understand what an event on iPhoto is and I don't know how to use it: for example I'm used to take photos with my mobile now and then so the pictures are not related to an event in particular like a birthday or a travel. They are just everyday pictures. So how can I manage them?
Again: I have some big folders of pictures related to some job experiences abroad. In that case the event is just "Germany job" for example? When I import the pictures iPhoto automatically create an event for each date of the folder, so it becomes boring to rename every single event.
Thank you very much

Don't get hung up on the Word 'Event'. I have Evetss called Spring 08, Autumn-Winter 05 and so on. An Event is just a Folder of pictures. They can mean whatever you want them to mean. When you import from a camera iPhoto will break the pics into Folders of Days, called Events.

iPhoto -> Preferences -> Events: Uncheck the box at "Imported Items from the Finder"
Now iPhoto will not attempt to split the Folders of Images.

i do wana know what is meant by user flag and how it is different from System flag.?
can i use user flag to distinguish the mail. in my application?
Thanks,

System flags are defined by the IMAP spec and every server has to support them.
User flags are defined by the application. Different IMAP servers may have different
limitations on user flags.

What are Color Moods and how can I use them?

Color Moods allow you to select color themes from an image based on a pre-set mood. Moods can be accessed by tapping on the flower icon after you take a picture. The preset Color Moods are: colorful, bright, muted, deep, dark, custom. You can experiment with each mood to see different color themes.
As soon as you move one of the cursors on the image, the mood setting changes to Custom. The custom Mood allows you to select specifc colors.

What are these features and how can I use them?

Why do I have SDM Profile, Dyanmic private IP, Pay per message, Mobile Hotspot provisioning, My mom is on the same account and does not have these. Everything I look at points to enterprise stuff and administration. I'm not aware of any of that. Verizon seems to act like they don't know but it's right on my bill. My VM seems to be funky too. I had to change my phone number because of unknown video texts being sent. Something is still not right.

If these are items listed on your account as features, I think there are supposed to be there.
I know I have that dynamic IP address one for my smartphone. So I suspect it is associated with the smartphone provisioning.
The mobile hotspot provisioning would depend on what kind of plan you have.
The pay per message is probably associated with your text messages so your phone will receive and send them.
The other one I'm not sure about, but it could be something associated with the SIM card.

I'm getting this error statement: XULRUNNER error: platform version 6.0.2 is not compatible with min etc max etc6.0.1 - what is this about and how can it be corrected?

This is what I think may have happened. The other day, Thursday Sept 8th, I shut down my pc in the middle of a Firefox upgrade. Now when I try to access Firefox on my pc, I get this error message:
XULRUNNER Error: Platform version '6.0.2 is not compatible with min Version >= 6.0.1 max Version < 6.0.1
What is this about and how can I retsore access to Firefox on my pc?

If you use ZoneAlarm Extreme Security then try to disable Virtualization.
Do a clean reinstall and delete the Firefox program folder.

If your Mac is new-ish and has one of the Lions as its OS, the drives, cards, USB sticks no longer show up, even though they're there. Go to Finder's Preferences and tick the corresponding items in the General and Sidebar tabs.

I just PAID for Black eyed peas Time of my life and now iTunes says I can't put it on my iPod 5th gen ? What? Why? And how can I get it on my ipod?

I just PAID for Black eyed peas Time of my life and now iTunes says I can't put it on my iPod 5th gen ? What? Why? And how can I get it on my ipod? And if I can't put it on my ipod how do I get my money back? I registered my ipod on iTunes, why was a song I can't put on my ipod even offered to me? What a rip?

Because you can only synce with one iTunes library and you are switching libries by using the new computer. To nake this yyour syncing computer:
- Move all the media(apps, music, synced video and photos etc) to the new computer.
- Connect the iPofd yo the computer and bake a backup fo the iPod by right clicking on the iPod under Devices in iTunes and select Back Up
- Restore the iPod from that backup.
Note that the backup that iTunes makes doe not include media.
To move mdia to the new computer see:
iTunes: How to move your music to a new computer
iTunes Store: Transferring purchases from your iOS device or iPod to a computer

Hopefully this will help you. Try placing your iPad in recovery mode again. You may have to try this a few times.

To use iCloud, you must first set it up with your Apple ID on a device with iOS 5 or a Mac with OS X Lion.
