Give full details of your device, 3G or 3GS, version currently installed.
Although this is not the right thread for this, but i will try to help you through otherways.
my device, a 3G/16Gb/ model MB501DN/MF 05.13.04 becomes also slow.It just freezes sometimes and reboots.
While rebooting it takes a long while to be ready.
