Palm Eos (or is it Pixie?): Thin, GSM, Awesome

When a webOS rumor rains, it pours.  Mere hours after we heard about some sort of "mini-Pre" and saw a blurrycam update, Engadget drops more details.  Here's what they're saying: it will be a 3G candybar headed to AT&T.  It will be 10.6mm thin (!) and 55mm x 111mm, weigh 100 grams, and have a 2.63" 320x400 capacitive touchscreen.

4 gigs of storage, the same 1150mAh battery as the Pre (and it'll be removable), $349 pre-rebate, A-GPS, MMS, 2 megapixel camera.  The. Works.

The codename is apparently "castle," which we had previously assumed was the codename for the Pre.

So, does this mean the Pre isn't coming to AT&T?  Will we see a CDMA verison of the EOS?  All the slider-haters out there are going to have a very tough decision on their hands if this rumor pans out (and it looks very much like it's going to pan out.)

Update: TechCrunch reports that the device (assuming it's the same one) is code-named "Pixie."
