Galaxy S III is getting a new SKU, with a new OS and LTE support.
The Galaxy S III i9305 has been listed for a while, but now you can actually buy one in Germany. However, LTE comes at a price. The phone’s battery performance is marginally lower compared to the i9300, it’s only available in black and gray,
and it costs a lot more.
The few shops that actually carry it are charging €749 for the 16GB version. That’s about €250 more than a comparable i9300 and it should probably retail for €549 rather than €749.
In other words, it’s probably best to wait for mass availability, or get it once carriers pick it up. You can check out the listings here
