I'm an ex iPhone developer. I had a developer account for a long time but I decided not to renew it because I'm a poor grad student who no longer has time for iPhone development because of my research. I was wondering if it was possible for me to revert from iPhone 3.1 beta 2 back to iPhone OS 3.0 because I hear 3.1 beta 2 will expire tonight. I installed beta 2 honestly with a valid developer account but my account expired 3 days ago and I am not able to download beta 3. Please let me know if this is possible to do without too much trouble. If not, I might have to bite the bullet and renew my account just to make sure I don't lose phone service at midnight!
