Hey guys, back from 2008, when i used to have an Ipod Touch (good old days of iLiberty and 1.1.4 (LOL). Anyways, i just bought (still dont have it, but it's on the way) an iPhone (2G) and it has 3.1.3. I've looked around and i've read on a lot of ways and a lot of messages telling me to or not to downgrade to 3.1.2, so i'll just ask directly. Which program should i use and why? What is baseband? The seller said it's carrier unlocked, i thought i should add that detail. Thanks in advance and i'm glad to be back!
