Howdy guys. I've just gotten myself an unlocked and jailbroken iPhone off eBay. It looks like it's an American one (it has AT&T listed on the box plus has a two pin charging thingy). Just one or two little problems though - it looks like it has an old version of installer.app, the one I've got on my iPod touch looks much different. I can't install SummerBoard - it says I need to be on firmware 1.1.1, so I try the old version but I get a message telling me that I need to have firmware 1.1.x? Is there a way for me to upgrade (or downgrade so I can start afresh) it to run 1.1.2? I did it on my iPod Touch with no problems, but I don't want to brick the iPhone or mess with the unlock situation. For what it's worth, the about screen says I'm running on 1.1.1 (3A109a) and my model number is Ma712LL. Any help would be apreciated, I really want to be able to install some actual apps.
