The next update to the G1 firmware will be widely available for over the air download on November 11th. The process has proven to be simple as users should grab the download and then drag to your included MicroSD card. T-Mobile does not fully support the download yet, so if you end up with a brick its not their fault, or ours for that matter. There is no official release on the things that are upgraded but users of the T-Mobile forums are reporting that the upgrade is really simple to do.
I am in the process of upgrading mine. It is really easy and you can follow the steps here, but only at your own risk, we are not responsible for messed up handsets. The update takes around five minutes to process. Mine has fully upgraded without problem and I do not have a brick! Yay!
