General gripes are 'Phone' and 'Mail' which I've discussed in another thread about losing the 'save images' option on multiple images received in 'Mail'. But since update to 1.1, I get more freezing and am seeing a blank screen when going to 'Phone' and sometimes the whole phone goes blank. There was a hint of this on 10, but this update has made that worse. Sometimes even restarting to reset it is not responsding either. Does anyone else suffer from it or is it time for a new iPhone?
