is your problem been resolved, i've been had the same issues
did u try this
double tap on HOME button, at the bottom you'll get list of all apps running in background
hold one of the apps there till it starts to toggle, once that happens there will be a ( - ) symbol
on the apps, just minimise all of them as that will free up your ipads RAM memory and then try the soft reset as advised by other forum users
Hopefully that should fix the problem as it helped one of my colleagues, but didn't fix the issue yet on my ipad 2
i'll be taking it an apple store
