hello everyone i need your help please
i can't find the facetime on my iphone i was using it before 1 month after that it's just disappear i need your help to get it back .
thank youFACETIME MISSING
The governments in some middle eastern countries have banned Facetime and it is disabled on iphones purchased in those countries. The countries include KAS, UAE and others. There is no way to get Facetime on such phones (for example it cannot be downloaded and installed) and taking the phone to another country does not cause Facetime to reappear on such phones. In support.apple.com/kb/ts3367 it says “Note: FaceTime may not be available, or may become unavailable, on devices purchased or used in certain countries, including Saudi Arabia and the United Arab Emirates. Check your device's region of purchase for more information.” -
Calendar message said if I wanted to save entries for more than a month I should go to settings and change to sync for 'all events'. I did this and all but repeating birthday entries disappeared. I have tried to reverse but nothing has reappeared. HELP!
Welcome to the discussions,
WHY does it claim to be 8G but my capacity now says its just 6.83
The size of you HD is calculated binary when it comes to use it, instead of decimal when companies want to advertise there products. 1 KB=1024Byte instead of 1000KB as advertised by the manufacturer. In your case this reduces the actual available space by the factor of 0.93 or approx. 7,4GB.
If you have an "other" section in your color bar showing the different types of data on your ipod, which is bigger than 500MB, this could be a sign of corrupt data caused by a sync that did not complete or copied damaged data. A restore will reduce the size to normal again.
Restoring: http://support.apple.com/kb/HT1414
If you restore your ipod, iTunes will install the newest firmware first and then add back your data and settings from your last backup if you choose to "restore from backup". Every backup is replaced by the following one, so make sure to include this folder in your backup routine in case you'll have to go back.
You can check the location and size of the backup folder for your ipod here:
Windows Vista and Windows 7: \Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\
copied from: About backups http://support.apple.com/kb/HT1766
Sorry, I can't answer your payment question, I have never used your kind of setup, maybe you can find something useful here: http://www.apple.com/support/itunes/ -

My old school palm pre was much friendlier than the IPHONE 3G. I was able to sync my outlook calendars and contacts via wi-fi effortlessly. I tunes did sync once or twice in the six months that I have had it, but more often it acts like it is syncing and ultimately delivers a message like "no calendar application is supported". Why the back and forth. Very frustrating after literally hours of trying to sync my phone with my Outlook calendar and contacts. HELP!!!!
What version of MS Office do you have installed? Have you tried re-installing office over top of itself? It may not be properly registered with the OS.

You cannot activate the iPhone without the AppleID and passcode used
to originally activate it. This is a security feature in iOS 7 called Activation
Lock. There is no workaround.

I do not have access to itunes store. I tunes store was working well with my old ipod with 30GB wich i had for about 6 years. I went to the store to have the battery replaced. However, I was told that my ipod was ready to be recycle. I received 10% discount to buy an ipod touch with 60GB +. When I connected the ipod touch to my computer, i did not have access to itunes store. Also, none of my music was synced. In addition, the icon for my ipod showed that the battery was not charged even though I charged the ipod touch for more than 8 hours prior to conneting it to the computer.
I have installed the latest version for itunes 10.6.1. Still I do not have access to itunes store. I have put more than 10 hours trying to solve this issue. I have become frustrated and ready to return my purchase.
Please helpHere is what worked for me:

I want to get iBook, Facebook and Skype to my iphone 4.2.1 through my iTune, but I coudn't because it is said that it requires a newer version of iOS. Please I need your help. Thanks
If your iPhone can't be updated to a higher iOS version then the only way to get them is if you downloaded versions of them which were compatible with iOS 4.2.1 and you still have copies of those versions somewhere e.g. on your computer or on a backup - only the current version of each app is available in the store, and as apps (and other content) are tied to the account that downloads them, you will need to have older copies that are linked to your id

I need your help, please. I can't get my photostream synchronized
Dear friends, I need your help again!!!
My photostream from my computer, windows vista, is not updating the pictures on my photostream in neither one of my IOS devices.
I'm sure that the photostream in both IOS are turned on. In my computer it is also turned on.
For example, I tranferred some pictures from a normal file to the photostream in the computer and I expected that them went also to my
iphone and ipad, but it not occurred.
Please, do you have some advise for me?
Thanks in advance.first i would try a simple restart of your computer and your iPad and see if they show up after they reboot. Also which folder are you putting them in? on windows there will be a seperate folder in the photostream folder that will show upload/uploads you will want to make sure they are in there. Also here are some basics about photostream to make sure you are meeting all the requirements and are not over your limit, http://support.apple.com/kb/HT4486

I need your help...I made a very big mistake!
I really need your help. A friend of mine has an iPod Nano and when I was helping him out on his PC, I accidentally spelled his last name wrong. As in, instead of Smith, I typed Smyth. Anyway, how do I remove that mistake in his iTunes and iPod? It's showing up as the wrong last name! I deleted the wrong name from every registry entry and also uninstalled iTunes and the reset the iPod. He said he resynched the other day and the wrong name came back. How can that be? How do I get rid of this BIG mistake on his Dell PC and iPod while not having it happen again? I'm never hearing the end of it now and so, I come to you for help. Thanks so much! Debbie
Thank you Jeff for the link! Between your link and Niel's response, I think I've got it. I'm going there today to fix the problem so this friend will leave me alone! (GRIN)
I really appreciate the help from both of you! Thank you so much! Apple people are such nice people! I think I just might buy myself a Mac and my own iPod!
Thanks again!

Need your help on performance issue please
Hello everyone!
I need your help to understand an effect I notice with a Thread class I built. I currently work on enhancement of my application Playlist Editor (see http://www.lightdev.com/page74.htm) and a new release will be available soon.
Among other extensions the new release will have a title filter function which is based on audio data that is recursively read from ID3 tags of files found in a given root directory. The data collection is done by a CollectionThread class which reads into a data model class AudioDataModel and the entire process works fine, no problem with that.
However, when my application is started for the first time the CollectionThread runs approximately 3 minutes to collect data from approximately 4300 audio files on an Intel Pentium M 1,4 GHz, 512 MB RAM, Windows XP SP2. When the application is shut down and started again, it takes only a few seconds to do the same task for all subsequent launches.
I already tried to start the application with java option -Xms40m to increase initial heap size. This increases performance in general but the effect is still the same, i.e. first run lasts significantly longer than subsequent runs.
I also tried to build a pool mechanism which creates many empty objects in the data model and then releases them to contain the actual data at is being read in but this did not lead to better performance.
It must have to do with how Java (or Windows?) allocates and caches memory. I wonder whether there is a way to pre-allocate memory or if there are any other ideas to improve performance so that the process always only takes seconds instead of minutes?
I attach the key classes to this message. Any help or ideas is much appreciated!
Thanks a lot a best regards
Ulrich
PS: You can use the news subscription service at
http://www.lightdev.com/dynTemplate.php4?id=80&dynPage=subscribe.php4 to be informed when the new release of Playlist Editor is available.
All classes posted here do not need debugging, they already have proven to run error free. The classes are only posted for information for the interested reader - no need to go through all the stuff in detail - only if it interests you.
My application calls class CollectionThread wich is a subclass of InfoThread. CollectionThread recursively goes through a directory and file structure and stores found ID3 tag information in instances of class ID3v11Tag which in turn gets stored in one instance of class AudioDataModel. All classes are shown below.
This is the mentioned CollectionThread

*Hi Franck,
thank you, mate. I did what you suggested (changed class attached) but that did not change the mentioned behaviour.
The first run is approximately 75 seconds with Java option -Xms40m and approx. double without, the second run and all subsequent runs are only 2-3 seconds each (!!!) even when terminating and re-starting the application between thread runs.
I'm pretty clueless about that, any more help on this anyone?
Thanks a lot and best regards
Ulrich
PS: BTW, I forgot to post the class that is filled with data by class CollectionThread, so here it is
