Thread: Iphone (original) SIM unlock
07-01-2012, 09:56 AM #1Iphone (original) SIM unlock
I'm having a hard time understanding if my phone (originally with ATT) is SIM unlocked or not. Firstly my iPhone was inactive when I jailbreaked it (i have bought a new iPhone 4 and would like to pass this phone on to a family member). So I have cydia running on it now (upgraded to the latest version). The version of the software is 3.1.3 (7E18) and the modem is 04.05.05_G. When I try to put in another SIM in from ATT(from my other family member. unfortunately I don't have bother sim from another carrier) it gives the connect to iTunes screen. I'm afraid to do that of course.
Again my question is as I believe my statement above might be slightly confusing.
Is there a way to check if the phone (on the phone itself) is SIM / carrier unlocked before I go overseas?

iPhone already jailbroken and has Cydia on it. Should i still use redsnow 0.9.4?

You have to restore and use redsnow to activate and unlock. Otherwise it will keep kicking back to activation when a different sim is inserted.
I suppose using SAM to hactivate and then boot neuter from cydia to unlock will allow you to do it without restoring. I just find it easier to restore and start from scratch.

Same problem with me also

There is no 9B209, I think you mean 9B208
And I'm assuming you guys have an iPhone 4.
If you updated from iTunes instead of using a custom firmware, you have updated your baseband to 04.12.01, which means you cannot use a Gevey Sim because that baseband is not updated
You can use redsn0w to hactivate and bypass the activation which will allow you to use it as an iPod
