I'm planning to downgrade from 4.0 to 3.1.3 on my 3G. In addition, I will also be jailbreaking and unlocking (I plan on selling it to a co-worker). However, I wanted to double check my plan of action. I figure it's better to foul up here than with my phone. edit: I'm on iTunes 9.2.1 (4) 1. Downgrade using http://lifehacker.com/5572003/how-to...your-iphone-3g to 3.1.3 2. Jailbreak using: (here's where I'm not sure about the plan of action) a. redsn0w_mac_0.9.5b5-5 b. redsn0w-mac_0.9.4 c. Is there another choice? 3. Unlock using ultrasnow Will I mess anything up if I choose to use redsnow 0.9.4 over 0.9.5b5-5? If it looks good, I'll give it a try within a couple of days. Thanks in advance.
