All human wisdom is summed up in two words - wait and hope 2.0 is around the corner. As your heart pounds faster, for some anyways, and as you get more excited with the new features coming, like MMS or the iTunes Control, be patient and dont upgrade. For you old timers, you know this. You know that you should always wait and not upgrade because if you do upgrade and there is no solution for it, you will end up with a bricked phone. For the newcomers, "wait and hope." Let reports come in of how 2.0 reacts to Installer and Jailbroken iPhones- In fact we know that 2.0 doesnt allow either, including unlocking. What we dont know, is what the "gold master" solution has that may further prevent unlocking and jailbreaking. Also, if there is another developer out there claiming to have the unlocking capabilities for 2.0, always double check with moderators and with old timers on hackint0sh.org to make sure it wont brick your iphone, or hard-code a MAC address to every iphone it unlocks *cough cough* Stay tuned though. You never know what may be coming or released in the next few weeks.
