We just got our 3Gs's last weekend. This morning I checked some mail and came back to it a few minutes later. All of sudden it would no longer power on. I know the battery was about 50% when I checked email. The phone has not been jailbroken. Hooked it up to the PC (windows 7) and Itunes said it was in restore mode which I have no idea what this really is. Itunes said to go ahead an restore the phone. I let Itunes start the process, but then Itunes gave an error code 28. I have no idea what this means. The phone has been flawless until this point. Any ideas would be appreicated. Thanks.
