Can you please help me. I purchased the new Apple I 4s phone from AT&T. I bought it out right. NO CONTRACT!! I paid almost $1000.00 for it. I then, had it enrolled it in my company's ATT service plan. They paid the bill for my service. Since, I have left the company. I have retained, and assumed financial responsibility for the phone, and the phone number with AT&T. The same day I assumed ifinancial responsibility, I had the phone number ported to a new service provider. ( Straight Talk ) After doing so, my phone worked fine. (as far as cellular service) NO DATA Service !!!! I have been on the phone with AT&T, Straight Talk, and Apple, FOR HOURS over TWO days!!! Trying to get this problem resolved. All I need to do, is change my APN settings (access point name ) settings. Its my phone!!! Why does any body have this APN menu locked from me??? I've been on the phone for two days between, AT&T, Straight Talk, and Apple products technical support teams. Everybody points the finger at the next guy!! What can I do to get the phone, that I paid for, work for more than just a phone, and a paper weigh?

PLEASE HELP ME!!!!!
