My 3Gs has the standard 3.0 that came with it, I'm missing out on some great apps that are 3.1 based and wondering if its worth it unfortunately I need the tethering feature hacked @help.BenM.at and wish not to loose it on an upgrade, is this possible? Would I have to deal with other snafu's with a Jailbreak work around, or can 3.1 tether as well?
