The listing, iPhone 3GS Perfect Condition!! GIN Bonus! has ended.
Wow, this cell phone is in perfect condition. There is a screen protector on the front, so no scratches, and as you can see of the back photo, the back is in such good condition it is like a mirror. We always kept it in a case for protection.
AT&T is the carrier, but we used it on one of the mobile virtual network operators, called AirVoice Wireless. The other MVNOs that run off AT&T that could be used are Black Wireless, 420 Wireless, AIO Wireless, Consumer Cellular, Divvy, GHz Cellular, good2GO Mobile, H2O Wireless, IQ Cellular, Jolt Mobile, Net 10, PureTalk USA, Red Pocket, SIM Shalom, and Straight Talk, per the Wiki list of AT&T MVNOs.
Since I was asked in one of the questions below, I might add that AirVoice has a $10/month plan,which my two boys have. It gives them data and 500 texts with 250 minutes. This is the reason I listed the MVNOs that run off AT&T in the listing. Its free to port your number to any of them, and since it only took me about 2 hours to have it processed, no reason not to be able to use this phone unless AT&T has bad reception in your area.
Phone only, I don't have an extra charger. Battery still keeps a great charge.
GIN Bonus: I will include a free airvoice sim for use with the phone, and a Minecraft case that we had with the phone that is also in great condition.
Good luck bidding!!
