I did a warranty exachange also. The phone I recieved was in WORSE condition that mine! My warranty claim was for the keypad...lights dim in different areas, and like the other was going out. Anyway. When I got my replacement...I opened the box and the sim card holder was floating around the box! WTF?
I tried to put it back on..but it keep coming loose. Seems whoever had it before broke it..and no..this is not a new phone for sure.
Anway...I put my battery in..and the keys are worse then my old one! I call them up..I was very calm and nice...told them what happened...they are shipping me another one.
Overall...Im very happy with T-Mo's team. Oh...and I did have to pay shipping for the first one...but not for the 2nd one.
