An admin in the T-Mobile forum posted a thread about the firmware version 1.1 / RC33 that have just been issued. The update will be available to all G1 users in the next two weeks according to the same post. The update includes several bug fixes and feature enhancements, but is not ‘Cupcake’.

Even that the announcement decline the availability of Cupcake in this update, there is at least one feature which is the ability to save MMS content that came from cupcake. The update will include obviously bugfixes and many enhancements, in addition to Google Voice Search for the first time after being available last November in iPhone.

Update will be sent between February 5 and February 15 according to T-Mobile.
