I'm finding out that the original international i9000 Galaxy S has 3 3G bands, 900, 1900 and 2100. The middle one might actually give 3G on select AT&T areas that has the 1900.
Other select i9000 variants may also have only 8gb but I don't know which ones. (i9000C? i9000B? For Chile and Brazil respectively).
In other news, seems like Galaxy K just hit the market. This for is for KT or Korea Telecom. It's packing Android 2.2 right off the bat.
