The Palm Eos smartphone is expected to start shipping in October, according to a DigiTimes report. The GSM/HSPA device will eventually be produced at numbers between 400,000 and 500,000 per month. A CDMA EVDO version of the device is expected to ship in the first quarter of 2010. This latest bit of news supports earlier reports that AT&T will get it first in North America.

To refresh your memory, the Eos features a 2.6-inch, 320×400 multi-touch display, QWERTY keyboard and a thickness of just 0.42 inches. The device would slot in under the Palm Pre, losing Wi-Fi and including 4GB of built-in memory and a 2-megapixel camera. Access to 3G networks as well as assisted GPS and Bluetooth are retained.

Following the confirmation of the Palm Eos for AT&T, PhoneNews is claiming to have insider information about the existence of a CDMA version of the Palm Eos that will work on Sprint’s network.

Supposedly, the lower-cost Web OS phone is currently testing at Sprint and should be available sometime in the third quarter, after the release of the Pre. Other than running on CDMA, it should be identical to the AT&T version. We’ll let you know more when we know more.
