This iPhone 3GS is on T-Mobile using 3.1. It was jailbroke with blackra1n. The first 5 # from serial number is: 84937 and modem firmware: 05.11.07
Can I just plug the iphone to my mac, use itunes to upgrade it to 4.1 (i don't care if I lose any JB apps or etc), then use limera1n to jailbreak it?
and would i need to install ultrasn0w to unlock it after JB'ing with limera1n?
