HTC HD7 might hit AT&T
The handset carried the model number PD29130, just a digit apart from the PD29110, which seemed to be the model name for T-Mobile's HTC HD7. Combine all these facts and you arrive at a conclusion that this would either be an AT&T-branded/compatible HD7 or just an HTC HD7 model slated for an overseas release as sometimes these pass approval as well. While we certainly hope that the first guess is right, we cannot be sure just yet.
The HTC HD7 is the only handset sporting a 4.3-inch display in the Windows Phone 7 lineup and it was definitely in high demand as it was put on backorder just hours after its launch. The device was reported to experience the “death grip” issue and lose signal, but HTC was quick to dismiss the problem and say that performance should still be sufficient for proper operation when you have adequate coverage. And even though AT&T already features three WP7 phones, the Samsung Focus, the HTC Surround and the LG Quantum, we would love to see even more variety at the U.S. second biggest carrier.
