i have an iPhone 4 iOS 4.2.1 firmware 03.10.01 and i want iOS 4.1 so i can have an unlocked iPhone...seems like the unlock for 4.2 may not even come out. willing to trade + throw some cash on top or buy it straight up. must be in good condition too. thanks!
Are you sure you can't unlock your 4.2.1? I have the exact same thing and jailbroke it, but I haven't tried to unlock it. A quick google search makes me think I could though.
yea mine is jailbroken too. they are actually working on it right now, but they've been working on it forever. here's the latest news for it though. http://www.redmondpie.com/iphone-4-4.2.1-4.3-unlock-2.10.04-3.10.01-4.10.01-baseband-in-works/ i guess i could wait til the end of the month to see what happens.
