1) Are you rooted yet?
2) Where'd you buy the phone from?
3) Are you on the original ROM you bought it with?
4) What do you see under settings > about phone > Firmware configuration version?
There's a chance your phone is actually running the same firmware as another country's. For example if you bought it from Expansys it's probably a UK milestone. In any case, if I read Wikipedia right, UMTS 2100 is the only frequency used in all of Africa. So your phone might be like the Euro/most-of-Asia 900/2100 version, but it could also be like the CDN/Thai/LatAm 850/1900/2100 version. You won't lose 3G from flashing the wrong one because they all have 2100, but you'd be best to stick to the closest one you can.
Now - if your phone is still in total stock condition, unrooted, then you have the opportunity to make a nandroid backup of the original state. Go to the root instructions using OpenRecovery. When you get to the stage where you're in the OpenRecovery menu, before you go and root the phone, make a full backup. Make two in fact - one with data, one without. And copy it somewhere safe.
