Previously, Sony’s newest flagship mobile device, the Xperia X10 was shown to have T-Mobile USA 3G bands. Quickly enough, most sites slated a AT&T launch in the States. But according to the folks over at AndroidGuys, the Xperia X10 seems to have two variants. According to the document they have received, the X10 is supposedly headed to Bell/AT&T AND our very own Magenta. The document shows that variant 1 has the 1700MHz band, which is exclusive to T-Mobile in the United States. Let’s just hope this turns out to be true. I sure would love to have that beautiful device, although it definitely won’t be anywhere near cheap. Hit the jump for the document, courtesy of AndroidGuys!
