Apps stuck in "Waiting" stage in iOS 5

The waiting happens all the time. It is not unique to iOS 5. To resolve try:

- Resetting the iPod. Nothing will be lost

Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at

least ten seconds, until the Apple logo appears.

- Download the apps on the computer and sync. They may alredy be downloaded if you have checked the option to automatically download purchased items to the computer/iTunes library.

- Restore the iPod from backup

I have literally TENS of apps on screen after screen on my iPad 2 that are in the waiting state. And there's also one in the background apps that come up when I double click the HOME button that refuses to quit/close. I manually closed the tens of apps, each time agreeing to delete them, etc., only to see them reappear again.

If I "Sync Apps" to my computer (rather than wirelessly in iOS5), I will lose my existing apps & their content, the folder arrangements, etc..

I wish I had a solution, but my IPhone 4 is doing the same thing! No help thus far with every recommendation offered thus far!
