This post is probably one of millions although I did search I couldn't find a straight answer to my problem so I'm posting.
I was following this guide :
http://www.winandmac.com/mobile/ipho...nd-jailbroken/
I was doing everything correct just like it says like in many other guides and then I get to the 1.1.2 unlocking step. I download AnySim 1.1.2u, set my phone in airplane mode, put my T-Mobile USA sim in and I run it. At the end it tells me its unlocked. So I reboot the phone and guess what, its lied to me. I cannot make a call or even get any bars and it keeps telling me that I cannot use an unactivated sim. I used the Baseband Downgrader to virgin the firmware or w/e its called and still it doesn't work?
To get my iPhone out of this state I restore back to 1.1.3 through iTunes and then I try again cause otherwise the OktoPrep thing doesn't go to well and the jailbreak tool tells me I have to install it. So thats my problem and I know im not alone. So please if someone could help me that would be great. Thank you very much.
