Hey I have a 1st generation Iphone jailbroken and unlocked for use on T-mobile. I have been out of the Iphone hack game for a long while and am currently stuck on Version 1.1.4 (4A102) with the 04.04.05_G Modem Firmware. I am not 100% on what method I used to unlock it originally but I believe it was done using the virginized iPlus 2.0 method. I have yet to update iTunes since I originally jailbroke my phone so I am currently on iTunes 126.96.36.199. I am just wondering if there is currently anyway I can upgrade to 3.0 and have my phone jailbroken and unlocked so it still works with T-Mobile. I am currently running Windows Vista and any help or any of you could give me would be greatly appreciated.
