8320 TMobile OS 4.2.2.171
To install this software on any 8320: (If you just purchased an 8320 from TMobile then you likely already have this OS on your device.)
1. Download and install the latest Desktop Manager from
here
2. Download and install the OS packaged linked above.
3. Delete the vendor.xml file located in c:\program files\common files\research in motion\apploader
4. Connect BB, open Desktop Manager and you should be prompted to upgrade.
To add vendor themes here is the link to the edited .alx files for this OS. There are IM alx's included as they were in the same folder and vendor coded to TMobile. When the other carriers come out with the 8320 this may allow them to work on the other carries. (just a guess on my part-
