Hi, I originally had a Iphone 4 but I sold it and got a Atrix. (I used the micro to sim adapter, also had the data plan/imei switched).

My problem is, today I received a Iphone 4 from my brother and when I put in my micro sim, its says "no service" or 'searching". Sometimes it will say ATT 3G but not for long. I know it can't be the phone since my bros micro sim works on it.

I tried hackivating it but, my sim is on the official att carrier so it didn't work. Anyone have any suggestions? Please lmk.
