there is help here,and i am not trying to sound like a dick but look around the iphone forum your solution has been posted about 20 times,once you get into it if you need help just ask,but you gotta do a little work.we are forum of friendly helpfull people but you cant just sit back and let us do all the work for you,so look around specifically the thread about writing prl and talk and text on iphone 4 ,then try and apply what is said there to your carrier and after you try if you need help then ask.this phone is not a great one to start out on modding,its difficulty level is high so it wouldnt hurt for you to take some time and just read around in the iphone forum to educate yourself on some of this tough phones tricks.i hope this helps
