Today Ericsson made big news with the official announcement of the Xperia X10. This new Android smartphone is far and away the most powerful mobile announced so far. Now that we know just what hardware this baby will pack, the only question remaining is what carriers will get this gorgeous new phone. Ericsson hasn't officially announced that yet, but the fact that they've unveiled it must mean that they are close to ironing out a deal.

Android and Me points out that the X10 could easily be coming out for both AT&T and T-Mobile. How is this possible? Because the Rachel packs WCDMA/UMTS 1700/2100, which means this handset is T-Mo 3G ready. The X10 also has UMTS 850/1900, which is AT&T 3G ready.

The folks at Android and Me have also heard word that Sony Ericsson is preparing for a big New York event. That could mean any number of things, but considering today's unveiling I think a carrier announcement is the most likely reason. So which carrier is it, AT&T or T-Mo? Either is possible, and both could be the answer as well. We won't know until a better leak comes out, or Ericsson makes an official announcement. Either way, Android fans have yet another reason to be very excited right now.
