Wondered if anyone else has experienced this. As of last night my iPad keeps prompting me for my iTunes password, even when not doing anything iTunes related. Then I lost all data connectivity (3G in UK on O2). Reset network settings seems to have fixed that but am still getting the iTunes prompt. Only thing I did yesterday was add an additional email on game centre, but am not having this problem on iPhone 4 so am thinking it's iPad related rather than iTunes. Any ideas??
