I've used Apple computers for some time and the IOS devices since the beginning. The upgrade to IOS 6 has been the worst experience with Apple upgrades EVER. I have an iPhone 4 (waiting for 5 to be delivered) and the latest IPAD, In both cases the upgrade got stuck at the last reboot - when the white progress bar is shown - with about 10% to go. This was not a case of impatience as I left them both overnight to complete. Going into DFU mode and trying a restore from a prior backup resulted in the same thing. The only way out was to set up the devices as new and start over. Crazy! I like IOS 6 but the upgrade experience sucked.
