My week old iphone 4 has been working perfectly for about 6 days and then last night I picked it up and pressed the home key and nothing. So I plugged it into my mac and it says it is in recovery mode and needs to be restored with newer operating system. Tried the restore and got an error 1600. Then held the on key and it turned on and was completely back to normal. Same thing again this morning, pressed home key and nothing. This time I got the restore to work and updated the software to the 4.1 version ( with the new bars) and everything seems to be OK for now. I have made an appointment with a genius but was wondering if anyone here had any suggestions? Thanks p.s. I have not put anything on the iphone but music and apps from itunes. I don't jailbreak or anything like that.
