I was interested in trying out the iPhone OS 4 Beta but don't have a developer account. I've seen people asking for a donation between $5-10 to add your UDID to their dev account so you can test out the new betas. Well I was searching around found a guide to upgrade to the new beta without registering your UDID. I followed the guide and it didn't work out. I posted for help on ModMyi and this gentlemen posted a reply saying to message him and he can help me out. He said he would add me to his dev account because I went through all that trouble. I thanked him and gave him my UDID to add. He said it registered it and I was good to go. So I installed the Beta and I get this. http://imgur.com/Obokb.png So I send him an email saying it didn't work. At that time I could easily just use blackra1n and put it in restore mode and just restore it back to 3.1.3 which I did. He emails me back and says he put in the wrong UDID and that he put me into a new slot and provided me a link to the Beta. He gave me iPhone2,1_4.0_8A230m_Restore(3gs).ipsw and I tried to install it. I get an error 1015 so I try ti restore it to 3.1.3 and I get error 1015 again. I've been trying everything and can't do anything!
