Which phone to buy with thumb keyboard?

[jacob600]

Can someone recommend some phones to look at. Here are the three variables to look at.
1) Must be Pocket PC OS.
2) Must have thumb keyboard. I would prefer to get a model with a retractable Thumb keyboard.
3) Sprint or PCS carrier.

Optionally, bluetooth or SDIO would be great but it is NOT a requirement. Any recommendations are appreciated. Thanks.

Right now, I believe the G1000 is about the only true Pocket PC Phone Edition that Sprint supports. They have a Toshiba device, but it's technically not a Phone Edition; it's a Pocket PC with a phone radio smooshed in.

The G1000's thumboard isn't retractible, though, and I don't think any currently-available Pocket PC Phone Editions have that feature.
