We just had some very interesting news come across our desk regarding the Xperia X10 from Sony Ericsson.  The much lusted-after handset with the top-dollar price tag is due sometime in the next 2 months.  While most sites (including us) had the phone pegged as headed for AT&T, the document we have says that’s only half true.

According to a white paper from Sony Ericsson, there will be two variants of the Xperia X10.  One for Ma Bell, and another for Big Pink.  Take a look at the image below and you what we’re talking about.

Variant 1: UMTS HSPA 900, 1700, 2100 | GSM GPRS/EDGE 850, 900, 1800, 1900
Variant 2: UMTS HSPA 800, 850, 1900, 2100 | GSM GPRS/EDGE 850, 900, 1800, 1900

We could be looking at two scenarios here.  One, the white sheet dated November 2009 was put out before final specs were completed.  The other… and we like this one… is that Sony Ericsson does plan to release one that works on T-Mobile’s network.  Still, we can’t imagine either AT&T or T-Mobile wanting to subsidize $500-$700 of the phone to entice customers.

Let’s hear what you’re thinking in the comments.
