With Google working on the Android OS updates code named “Cupcake” in the works, it was not sure when and what updates will be made available for the T-Mobile G1. Well today the second part of the question which is the “What updates” has been partly answered.

In a note received from HTC by the gadget site Engadget, HTC states that they are confident of seeing most of the “Cupcake” updates pushed on to the T-Mobile G1 soon. Just to refresh, Cupcake is expected to offer a number of application enhancements, including bug fixes, a video recorder, the ability to save MMS attachments, better bluetooth support, better HTTP handling and, most importantly, a new JavaScript engine built on SquirrelFish.

However, HTC also made it clear that they have no control over this situation and the decision is up to T-Mobile.
