Phone Needs Unlocked With SIM Card - A Quick Question About It
Hi there, so my girlfriend just got an iPhone 3G from a friend of hers yesterday for the wonderful price of free. Problem is, it needs a tiny bit of TLC (which I'm more than capable of doing and have already started, I'm just waiting on parts to arrive) and it'll need to be jailbroken so that I can use it for T-Mobile.
I know how to jailbreak the phone (it doesn't look too terribly hard), but as of right now, the iPhone tells me to insert a valid SIM card so that it will be activated when I turn it on. If I plug it into my computer, iTunes tells me the same thing.
Now I have a good friend who has AT&T, and I'll be seeing him on Thursday night. Can I simply pop his SIM card into my iPhone so that the phone will activate/unlock and I can use it like an iPod Touch? The wifi signal flex cable is busted on it so I know I'll have to repair that before the wifi works on it, but it'd still be nice to just have it get this far, that way I can jailbreak it.
Assuming this method of borrowing a SIM card works to get the phone itself unlocked, will this also make the phone appear "working" or whatever you'd like to call it to my iTunes? I obviously don't want to keep his SIM card, and I use a desktop, so I wouldn't be able to verify it with iTunes until after I see him and try the phone unlocking thing.
Also, assuming that this will make iTunes have no issues recognizing the phone, what free jailbreaking program other than www.jailbreakme.com do you guys recommend? I already have Redsnow RC16 downloaded and ready for use, but if you know of something better, by all means let me know. Thanks a ton and I really appreciate all of the great DIY guides!
