iPhone 3gs, jailbroken/unlocked - ($120)

Happy friday,
I am going to sell my iPhone 3GS that has served me so well for the last years. The phone is unlocked for any carrier and I have been using it with my T-mobile Pay As You Go contract. The phone uses the bigger simcards.
*The battery is great but sometimes when I charge it, the phone says "Charging is not supported with this accessory" -but the phone still charges.
*The casing is a bit rugged as expected for an used iPhone.

These are priced from $150 and upwards on craigslist but I would sell it for $120 or the best offer. Will sell on monday.
Enjoy the weekend
