There are reports that Samsung will soon launch a new phone - the i5700 Galaxy Lite, a smaller-brother to the i7500 Galaxy. It will have only 1Gb of memory (and a microSD slot) and a 3.2mp camera. The display will still be an touch AMOLED, although it's not clear whether it'll be the same display as the i7500 (3.2" HVGA, 320x480).
The i7500 (with a 5mp camera and 8Gb of memory) is available in Europe, and some countries around the world. In the US it can be bought unlocked for 699$.
