I have a Verizon iPhone which was lack connected to my MacBook Pro over a month ago when I had Snow Leopard, before Lion. The iPhone is running 4.2.8 but am aware of a newer version being out. I would assume I wouldn't want to upgrade to the latest firmware, assuming there isn't a jailbreak for it quite yet...or at least an untethered JB? I performed a complete erase and reinstall when migrating from SL to Lion, meaning either way upon connecting my iPhone to my MacBook Pro, my iPhone will need to be erased and will have to reinstall all my apps and add my music all over again. I have no problem having to reinstall all my apps and media, I just don't wanna go without a jailbroken iPhone.. Advice?
