My iPhone 4 became unusably slow after an update I could not revert. I liked that device and would have preferred to have it still work if needed in a pinch. edit: To be clear I would have preferred them not force the upgrade on me. I still would have likely purchased a new phone, but instead I purchased an android phone.
