Okay, let's be completly honest, I know absolutley nothing about iPhones and their operating system. Not to long ago a friend of mine gave me his old iPhone 3g and I believe jailbreakme.com was used to unlock it and all that jazz so I could use on T-Mobile. Now the problem I am running into is that my service will drop out for anywhere from 2 min to 4 hours. I am not sure if this is a normal problem or if there is something I can do to increase my signal strenght. Again a complete novice, i keep hearing things about snow this and that but don't want to accidentally mess anything up. ANYONE WHO KNOWS WHAT THEY ARE DOING PLEASE HELP!!!!!!
