The only 3G providers, aside from T-mobile, are Vodafone, E-plus, and O2 is what I can surmise.

I already my phone with yellowsn0w installed, I just want a good data plan to go with it. Also, it should be as simple as getting a sim card from one of those providers and popping it in my phone, yes? I shouldn't need a simcard adapter or anything.

If you are on BB 2.28 and running YellowSn0w then you wan't need anything else, just put in your new SIM and away you go.
