I am on my my 5th iPhone at the moment, after returning four for various defects. My latest one is ok, apart from it is the first i have had with a yellow screen. I want to try restoring the software from 2.0 54345 to 54347. However, i no longer have the software restore file (i think it ends in .ipsw or something). So, i have two requests: a) Does anyone know where it is stored on a mac after iTunes downloads it? If so, i may be able to find it on my Time Machine disk. Or... b) Does anybody have a torrent link for it, or would be kind enough to put it on a file sharing website? Help would be much appreciated. Alternatively, any other tips on removing the yellow would be much appreciated!
