Granted, this particular bit of news is only valuable to the (very) small crowd of people who purchased the T-Mobile Garminfone, but it's nice to hear nonetheless. The good news: Garmin has released an update to Android 2.1 (Éclair). The bad: it's a manual update.
The update process isn't complicated per se - but it's definitely more work than an OTA:
1. Download the software update package for your Garminfone which can be found here: http://www.garminasus.com/en_US/support/software/006-B1130-00.update
2. Connect your Garminfone to your computer using the USB cable provided in your box
3. Select "File Transfer" mode when the "USB connected" dialog appears
