AT&T thinks your smartphone needs more functionality, so it’s published an update to the popular 8525 that grants many multimedia features for free. Users now have access to XM Satellite Radio Mobile, push to talk, and Sex and the City. Truly an important download.

All new 8525’s will have the update pre-loaded. What’s more, a free Windows Mobile 6 upgrade will be available later this year. That’s a lot of free for smartphone users.

We’re guessing AT&T is going to be aggressive with its smartphone updates, creating more value for users of the high-end handsets. Now you won’t feel so dumb about giving heartless carriers your $400, will you.
