same here, ive owned the device for just over 3 months. i now get error prompt underneath wifi when i try to turn it on, device is sitting next to me as i write this and its reboots itself every few minutes even if the screen is locked.
on power up i get process errors from some installed Apps from SD card and a storage.com error from Tablet preinstalled apps, possibly some of the errors are due to the tablet not seeing internet so they could be related.
One issue that confuses this is uninstalling apps from memory they show to uninstall ok, upon the deivce rebooting they are back there again. it makes me think the device is no longer in its general user level, but wouldnt explain why i wouldnt get a prompt that would say user privelage etc.
If possible i may try to get the 2.3 firmware to reblat it if Mods or storage cant help. has anyone had a smiliar issue and has a fix?
