New internal T-Mobile documents confirm the myTouch 3G with 3.5mm jack (aka myTouch 1.2) will be available in limited quantities starting February 10. This device is a clone of the T-Mobile myTouch 3G Fender Limited Edition minus the Fender. New additions to the phone include a 3.5 mm headset jack and 288 MB of RAM (vs 192 MB of the original MT3G). The new refresh of the myTouch 3G will replace the original MT3G black and white models.
The original myTouch 3G is still going for $149 (with 2 year agreement) and we expect a similar price for the refresh. The myTouch 3G with 3.5mm headset jack will ship with Android 1.6 and we expect T-Mobile will upgrade it to Android 2.1 in Q2 2010.
If you are a current T-Mobile looking to upgrade your phone, we suggest you wait a couple weeks and see what gets announced at the Mobile World Congress show. We expect HTC, Motorola, and Samsung will unveil new Android phones.
