Hi, ****WHY IS NOONE LEAVING REPLIES AFTER VIEWING THIS***** I am confused about this unlocking or jailbreaking method, and have several questions. Are there more advantages to unlocking my phone other than adding 3rd party downloads? Would reception be better on another carrier (such as T-mobile) as opposed to ATT's, (I live in the Washington Dc area and ATT's signal sucks and my friends who have an unlocked iphone claim they miss a significant amount of calls)? Do i initially have to activate the phone and sign up for a plan through ATT? If so if i were to switch carriers with the unlocked phone do i sign up for a plan with them? Does that mean more activation fees? Would i still have to keep a plan with ATT? Is unlocking your 3g iphone really worth it in the united states, or just more for international users? I know that verizon or sprint (which i have now and love the reception)does not work with the iphone, but i saw someone posting about an international sim card from verizon that works with the GSM, do you know if this is true? Thanks for answering I have tried to find these answers online but have not realy gotten a clear answer? JUST ADDED***** Also i was looking at this site for the jailbreak and help anybody used these guys? Iphone-sim-unlock.
