ok so i switched from sprint to at&t back in july and got an iphone 3g. i abosultly love the phone, love at&t's customer service and website, however i HATE at&t's coverage. it has been a nightmare, i drop calls all the time, i don't get service nearly the places i had with sprint, and just random things happen to my signal. that being said i am not here to bash at&t because i think they are a good company, just not right for me. so in a nutshell i am going to pay the early term fee with at&t and go back to sprint. my question is after i port my number back to a new sprint account i will be selling my iphone to one of my friends. will i need to keep the sim card or include that in the phone to her? i just didnt know if she would need it (she plans to have it unlocked to work on tmobile.) thanks!
