said by Cthen:Is there a way I can revert back to the old version? I am so not happy with this "Ice cream sandwich" update and would much rather have things back the way they were before the update screwed things up.
This is a reason to not be a first adopter and wait to update until you see others experience with you especially older or minimal device.
As OS grow they become more CPU intensive, on older processors that can really slow things down.
A major issue with older iPhones upgraded to iOS7 that really can't handle it, but Apple allowed it.
Same thing happens with Android on limited resource devices... that are updated, when maybe they shouldn't have been for their capability.... unfortunately going back can be very difficult.
