I've just bought an iphone 4, got home and my trusty old G4 wont see it, it says i need osx 10.5.8, i'm only on 10.4.11, my processor speed is only 733. from what i can tell i cannot upgrade to 10.5. is there anything i can do, i suppose jailbreaking it will let me bluetooth things to my phone-mac but did'nt wanna do that. any suggestions would be much appreciated. Thanks Jake
