Things are all cyclical, aren't they? First, T-Mobile was the early adopter and only supporter of Android, then Sprint stole the shine by releasing the HTC Hero, then Verizon took them all to town with the release and ad onslaught of the Motorola DROID. Now there's rumors flying around that point both the HTC Passion and Sony Ericsson XPERIA X10, two highly anticipated Android phones, to T-Mobile. If all true, once again, T-Mobile will be the carrier for Android devices.

Tmonews is hearing that the HTC Passion, the device with a 1GHz Snapdragon Processor and immense touchscreen, will be available on T-Mobile. The launch is targeted for January but we're not sure how the recent delay affects the release. There's little detail on anything else. Even though rumors are pointing to T-Mobile, we still wouldn't rule out a Verizon release just yet.

For the Sony Ericsson XPERIA X10, we had originally pegged it as a future AT&T device but it looks like that has changed. AndroidGuys has a document floating around that lists the 1700 MHz band (the T-Mobile 3G specific band) on the XPERIA X10. Since, no other carrier uses 1700 MHz like T-Mobile does, it's rather safe to say that it's heading to Magenta.

If T-Mobile does pull this off and carry two flagship Android devices at once, it's going to be huge for the carrier's brand, growth, and future success. We're definitely excited to see T-Mobile get back in the mix at the high-end for Android, they definitely deserve it after investing and believing in Android before anyone else.
