Unless I'm reading something wrong on the HTC Sensation's specification page, it looks like it does not support HSPA+ or AT&T 3G bands:
* Europe/Asia/T-Mobile US: 900/AWS/2100 MHz
* 850/900/1800/1900 MHz
Network bands in regions other than Europe and Asia Pacific may be different, depending on the mobile operator and your location. Please check with your mobile operator.
The next phone I get will have to support AT&T's bands as well, as I don't want to replace it at the end of the merger, if it occurs.
Can someone clarify this situation? Are there two sensations?
