I have TMobile Sidekick 4g's, 2 of them. In the year I've had them, several new versions of Android have come out yet TMobile, and or Samsung, have not seen fit to push updates to these phones which are currently using version 2.2.1. This seems sort of like abandonment to me, forgetting about caring for existing customers. Is there some sort of update schedule that anyone may be aware of that TMobile may have somewhere? Thanks.
