Iphone 4S 16GB factory unlocked with IMEI box (Original USA)

This is not a business add, it’s a personal add.
Got an Iphone 5S. So want to sell my Iphone 4S 16GB. Not a single scratch on any side. I bought it from USA. I bought it unlocked and contract free from T-Mobile USA. The Phone is 140gm. CPU Type is Apple A5. SIM tray is IMEI matched. Any SIM can be used. It’s not like other original Iphone 4S which are without IMEI matched box (Just fake box without IMEI) from Thailand or Malaysia (120gm) based production that is available in Bangladesh market. It’s originally from USA. I’ll provide all original accessories. I will provide Iphone 4S with IMEI matched Box. The things I’ll provide are:
1. Iphone 4S 16GB (No scratch and factory unlocked)
2. IMEI matched Box
3. Original charger
4. Screen Protector (Attached on Both sides)
5. USB Data Cable
6. SIM eject pin
7. IMEI Matched SIM tray
8. All Iphone Manual
9. iOS 7.1.1
10. No headphone (Headphone was damaged)
11. Iphone Smart Black Cover
IMEI: 013183005343222

It was single handily used for 4 months. I have uploaded all recent 100% original pictures here. If any serious buyer has any question regarding the phone, then feel free to ask.
