At the top of each model forum (Curve, Bold, Storm, etc.) there is a sticky with the latest OS version available for that particular model. In the case of the Curve forum, there is a listing for each individual Curve model: 8300, 8310, 8320, 8330, 8330m, and 8350i. No mixing/matching! You need the OS designed for your individual model.
Because the OS updates are released by RIM but only modified by the individual carriers with branding, you can use any carrier's OS with your BlackBerry. Using the Singtel OS on an AT&T BlackBerry is perfectly fine.
When we talk about the particular version of an OS we're using we refer to the app version. Major changes/updates take the OS from 4.5.x.xx to 4.6.x.xx and 4.7.x.xx. Smaller changes - usually bug fixes - are reflected in the last digits I listed above as "x.xx". So 18.104.22.168 might get a bug fix and become 22.214.171.124.
Just remember to stick to the OS for your exact model, and follow the updating instructions in the FAQ section. Piece of cake! It looks way more intimidating than it really is.
