I have been using 3.0 beta, but now i have a pink screen on my phone and iTunes says that that version of software i have been using has expired. my phone is unusable. I have been trying to download the official 3.0 version but have been receiving an error message. That stats, " there was a problem downloading the software for the iPhone. That requested source was not found." I have no idea what i should do. Can someone please give me some help.
