I was given the Ic502 phone by my job they pay for the monthly bill. I don't like the phone (no camera-email) The service is through sprint I beleive cause my email address to the phone is my phone# @messaging.sprintpcs.com. If I buy a Centro can I just switch the sim card and have everything work? I know I will lose the walkie talkie but I am ok with that as long as I have email and a camera. If not do you know what phone I can use with the sim from the Ic502? Thanks in advance.
