Bought an iPhone 3GS. It had never been jailbroken before; the previous owner just used AT&T. I have a T-Mobile SIM Card.
I upgraded to iTunes 9.2 & iOS 4.0.1
Can't use PwnageTool 4.01 b/c the iPhone has never been previously jailbroken. I also can't use JailbreakMe.com because my phone just tells me to insert a valid SIM Card... I can't even access Safari on my iPhone to visit JailbreakMe.com
Are there any solutions for me?
