I'm new to the iPhone world and recently picked up an iPhone 3G. My buddy has his running BlackRa1n and I was hoping install it on my device as well. Unfortuantely he told me since I had version 3.1.3 I would not be able to install in. Is there another Jailbreak that I could use that is equal to Blackra1n? I'm keeping this iPhone on the AT&T network so unlocking isn't important to me. Thanks in advance for any help.
