This here is the i856 from Moto, featuring a 2.2-inch display, 1.3 megapixel camera, Bluetooth 2.0, microSD expansion, and... well, of course, push-to-talk. By GSM or CDMA standards, it's not much of a phone, but you're going to be hard-pressed to find another slider (particularly one that puts half an effort into looking good) on iDEN airwaves -- and on a carrier like Boost, we can see this playing pretty well.

If you're willing to give up daytime talking, your rate goes down to $30. But up until now they haven't had a good affordable texting phone with a keyboard.

That will change when the Motorola Clutch i465 goes on sale next month.
