Hi,
I wouldn't wait for an update.
Try restoring your iPad.
Instead of restoring from a backup (which might re introduce the problem all over again), restore as new, instructions
here.
Then sync 3 or 4 apps at time, test your iPad. It's more then likely an app causing the problems.
Also, with your iPad connected to your computer, launch iTunes. Select the Summary tab. Make sure there's enough storage space. (It's not memory)
