Hi all, I need some help here in making a decision. I'm looking to buy an unlocked smart phone for t-mobile. I've read some issues of most phones not working over 3g on t-mobile due to frequency issues and i'm curious as to which would be a good purchase. I'm planning on keeping with my current no contract plan and just adding data service. Is there an android phone which is capable of using the 3g on t-mobile? Or what have been your experiences using t-mobile and unlocked phones with data service? Any advice or suggestions on this is much appreciated. My budget for any phone is around $600. Thanks
