Can you use a locked att iphone with straighttalk?

Is it possible to use a locked att iphone with straighttalk 45.00 a month plan and will mss and data work

Omg i would love to know the answer to this too!

Yes, it will. You just need to get a StraightTalk SIM that's compatible with AT&T and trim it to micro SIM. You'll have MMS and Data on your phone. It it fails, unlock the iPhone.

You need to unlock the iphone to use with straight talk

No you don't need to unlock it you just use the at&t sim y awnser if you don't know what your talkn about?

Penney, I have the same problem! AT&T doesn't want to unlock my phone because it's still under contract. Obviously I'm willing to pay the early termination fees, but they said I have to wait for the next billing cycle. So, I'd have to cancel my service with AT&T before the end of this billing service, wait until I receive the new bill (without any phone service), pay, and only after then they would unlock it! WTH! They don't let me pay now. Doe anyone know if there's another solution to this? Thank!

Penny @ guest - please try punning ST SIM in your unlocked phone. It will work
