Just bought unlocked/jailbroken iphone, some questions please

[sleepy180]

Ok i just bought a 1st generation 8gb iphone off of ebay. It said it was unlocked and jailbroken with 2.2 firmware. When i got the iphone, everything seemed like it worked alright.

So i figured i'de put in my tmobile simcard and be on my way. But instead it is giving me "Different Sim Detected" please connect to itunes with the itunes logo and i can only make an emergency call.

I didn't want to get all deep into iphone hacking and the like, but now it seems like i'm going to have to. Can anyone help me out?

Why is it not accepting my tmobile simcard?

Is it safe to connect to itunes? I have itunes 8.0.1.11 installed on my computer.

If i restore the phone to factory in itunes, will it brick the phone?

What are the things that i cannot do with this phone? Can i use itunes freely? Can i update itunes? Is there anything that i should know so that i don't brick this phone.

Thanks, i've been searching and searching and will continue to search after this post, but any help would be appreciated.



edit: also should i use this guide http://www.iclarified.com/entry/index.php?enid=1755 to unlock/jailbreak my phone again? And should i restore my phone first (if that doesn't brick it).

You need to use QuickPwn to hacktivate it. From there, you can unlock it for real if it still doesnt work.

I dont know why the person you bought it from didnt do this.

Usually "Different Sim Detected" means it was not activated properly, and "Invalid SIM" means it is not unlocked, if I remember correctly.

You can restore the original firmware if you want, you wont brick the phone. You can also run QuickPwn on a clean 2.2 if you want to start from scratch. The unlock will not be effected if you do a full restore, but you will still need to hacktivate the phone to use tmobile.

does quickpwn = same as winpwn?

And are you saying that i should just follow that guide that i posted in the first post exactly as the phone is right now?

And will my updated itunes work because in the guide it says use itunes 7.7 but it may just be outdated.

Thanks for your help man.

WinPwn is QuickPwn for Windows, I believe.

+1 You need to update your iTunes to at least 8.0 or 8.0.2, either one will work. B/C firmware is 2.2 and that's compatible with current pwnage/qwkpwn...
