Garmin’s nuvifone M10 made an appearance on the FCC today, thanks to a filing by ASUS.  The Windows Mobile 6.5 device features Garmin’s navigation software, along with the company’s Connected Services that provide real-time traffic info, gas prices, flight status updates, access to safety camera feeds, and more.

In terms of hardware, the M10 features a 3.5” resistive touch screen, 512MB of RAM, 512MB of ROM, 4GB of internal Flash, a 5 MP camera, microSD expansion, WiFi, Bluetooth and of course GPS.  The M10 is a quad-band GSM/EDGE device with support for WCDMA bands I and VIII, all powered by a Qualcomm MSM7227 processor running at 600MHz.

Garmin plans to release the M10 in Europe and Asia in the first half of 2010, while the company hasn’t yet announced plans for a US release.

The FCC filing from ASUS, above, reveals a PDA phone with the model 0100084.  Interestingly, the brand for this device is listed as ‘NA’ in FCC filings, and the FCC label for the 0100084 does not show any brand, either.  This suggests that ASUS is the OEM manufacturer for the 0100084, and the phone will likely be re-branded when it is released.

The test report for the 0100084 reveals support for 850/1900 GSM and WCDMA Band IV.  These frequencies correspond to T-Mobile’s service in the United States, indicating that the 0100084 may be a new smartphone for T-mobile.

Other than that, we don’t have much to go on.  If reports that the Nexus One will be released for T-Mobile are correct, then it appears that T-mobile will be making a big smartphone push in 2010.
