Palm EOSThe Palm Pre isn’t even in the market yet, but the tech bloghosphere is already buzzing with rumors of an upcoming mini-Pre phone.

The device, dubbed Palm Eos, will supposedly be Palm’s next webOS phone. Engadget reports that it is codenamed “Castle”, while MobileCrunch also calls it “Pixie”. Other bloggers give it the nicknames Mini Pre, Palm Pre Mini, and Pre Lite. Can we also call it Palm Pre Nano? :p

While the yet-to-be-released Palm Pre will initially be sold exclusively by US telco Sprint, the Eos will supposedly go to rival AT&T.

Engadget posted these specs:

* 4GB storage
* Price: $349 (pre-rebate)
* Camera: 2 megapixel fixed focus digital camera and flash / video capture
* Connectivity: Bluetooth 2.1 w/ A2DP and EDR, USB 2.0 via micro USB
* Removable 1150 mAh battery (4 hours 3G talk time)
* Messaging: SMS, MMS (picture and video only), integrated IM client
* Contact sync with AT&T Address Book
* MediaNet
* Cellular Video
* Email: POP3, IMAP4, and EAS support
* A-GPS
* Audio: WAV, MP3, AAC, AAC+ ringtones
* Video Playback: MPEG4, H.264, H.263

Engadget readers’ reactions to the reported device vary. User oghowie says “Pre looks better and is better spec wise. This looks like a lower end Pre.” On the other hand, reader Reality Check noted that this rumored device has no Wi-Fi, has only 4 GB of storage, and is more expensive than the iPhone. He concludes: “Pre wins.”

Of course, actual pricing may still change, but for now , I tend to agree that the Pre is better. The wait for the Pre continues, and Palm fans on our side of the world are on the lookout for any mention of a GSM Pre.
