    Hey guys, im really hoping someone can help me out here. I have a iPhone 4s (model A1387) that was originally w/ sprint. My roomate had it unlocked and switched over to T-mobile and had no problems. He gave me the phone and I upgraded to iOS 7. (I know it removed the unlock). I still have the same GPP and a new SIM card. I got it unlocked using a program called R-SIM NANO3G. It also installed an APN profile called China Unicom APN and a provision called mixtool (pic below). Now heres my problme. The top left of my screen says T-Mobile (good) I can make and recieve calls and I can receive SMS but I cannot send SMS, send or receive MMS or access the web. I went into setting/cellular but there isnt the normal option for entering APN info or anything (see pic below). T-mobile has been no help. Can anyone help me out here?IMG_2720.jpgIMG_2721.jpg
