T-Mobile MyFaves and latest OS

[bloodbath]

I would like to update my T-Mobile 8320 to the latest OS version, but I've read it's an AT&T version. I still use MyFaves, and so, was wondering if I could use this version? If not, which would be the latest T-Mobile version and were might I find it? (I do not want the US version - 4.5.0.81 - since it contains the browser security bug). Thanks in advance.

4.5.0.81 is the most recent tmobile Os version for the 8320. you can go to link to check for any current tmo OS. You can always use the myfaves no mater what phone you have but you have to go to t-mobile.com and update your faves there. You don't have to have the circles to get your free minutes to those 5 people.
