The Bold 9700 has seen a fair amount of OS updates become official lately. Today T-Mobile released BlackBerry Bold 9700 OS 22.214.171.1244 to their customers. Normally anyone can download carrier releases operating systems, however T-Mobile has a special download page that is only available to T-Mobile customers, therefore you need to have a T-Mo number to grab this update.
Not to worry though. If you aren’t a T-Mobile customer (or maybe even if you are) I would suggest checking out OS 126.96.36.1993, which was officially released by Rogers last week. This OS is said to run awesome on the Bold 9700. You can download the Rogers 188.8.131.523 here.
