You may remember our previous rumors pointing towards a T-Mobile release for the upcoming Sony Ericsson Xperia X10 handset, but now we have yet more concrete evidence that the phone will be releasing on T-Mobile along with AT&T.
As reported from BGR, an FCC document leaking the operators manual for the Xperia X10 was found, and it is on page 3 of this manual that reveals the juicy details.
If you take a look at Page 3, you’ll see that the details ‘3G Bands 1, 4, and 8′ are included, which BGR states that they are the AWS 3G bands that T-Mobile uses.
Basically, this is as close to a T-Mobile release that you are going to get, without the carrier actually making things all official.
Let us know your reaction to the news.
