can anyone tell me how to update my unlocked 3.0 iphone to the newest 4.1( i think?) i have been watching tutorials on you tube and they say to use red snow but when i go to open the links it says they no longer work? I also have a old mac power book G4 if thats important (OS 10.58).I'm desperate to download some apps on my phone but my old 3.0 says its just too old:(.
please help..step by step. thank you!!!!
