Our friends over at WMPoweruser have caught wind of some interesting info. Looks like 2 WP7 devices have shown up on DSLReports, a mobile speed testing site. Both were using AT&T’s network. The first device is a LG C900 and the other is the HTC T8788. We know pretty much nothing about either device other than their model numbers and that they will run WP7. There is a now an increased likelihood they will come to AT&T, however it’s not a guarantee as Microsoft, Samsung, or HTC could simply be testing them on AT&T but not for AT&T. Try as I might I could not find the HTC T8788 on the DSLReports page, but there were multiple instances of the LG C900 and Samsung Taylor listed.
