Thanks! Yeah, that's what I've been using it for, pre-paid service with Straight Talk. I unfortunately don't have the box/accessories. I myself bought it off CL not long ago, but looked up the serial # on Apple's site, so the guy I bought it from must have just gotten it since it's covered until 3/2013.
But other than the box/accessories, it's a 100% legit mint iphone. I think I'll throw it up at $600 and see what I can get. I know CDMA phones generally go for less, but this can be used with either CDMA or GSM with the included Gevey Ultra S sim.
I should point out, there's NOTHING wrong with the phone, only reason I'm selling is because I decided for ME personally, I'd rather just use a regular AT&T phone since I'm using an AT&T Straight Talk SIM anyway, mostly to avoid trouble when io6 drops later this year. Because the Gevey unlock will probably mean that you can't update until they update their technology for the new OS. That said, it's still a legit phone 100% usable for GSM sims (I'm using it with one right now).
