Hey guys, I want to use some apps that are 3.1+ only. I am currently on 3.0. I would upgrade, but I want to keep tethering. What's the best way to do this? Do I have to jailbreak? I could truly care less about any of the other things that come with jailbreaking, I just want to be able to use the newest apps and keep tethering. What's the best way to do this? Thanks!
