T-Mobile has begun pushing out an update to all Sidekick 3 owners that will make their devices compatible with My Faves plans. The update includes a My Faves application to choose numbers for the calling plan as well as other improvements to the software. Users will finally be able to quickly call or message contacts from the address book, save picture attachments from email to the phone’s gallery, and see a character count in the SMS compose window. The updates begin today and will be pushed out to all Sidekick 3 users over the next month.
