When trying to update all apps, I get This app is incompatible with this ipad. What do I do?

Thank you for your question. I'll do my best to assist you.

It seems like you've just updated your iPad to iOS 5, haven't you? This sometimes happen when you have the latest operating system on your iPad but the update for those applications are not for iOS 5. Or probably the other way around, where you still have the older version of iOS but the updates for those apps are for devices running on iOS5. If that is the case, try doing these stuff bellow.

1. Update your iTunes
2. Create a backup of your iPad in iTunes
3. Update your iPad to the latest iOS
4. Do a restore from from Backup
5. Then try updating those apps again.
