Samsung Infuse 4G. Available 5.15.11 in the States. As a current iPhone 4 owner I won't make a decision about my next phone until we see what iPhone 5 entails this fall. However, I love the screen on the Infuse (4.5"). The Infuse is also thinner than the iPhone 4 and equal in weight. Granted their are other factors to consider (Android of course, etc) but I want to play with this model when I can locally. 3.5" screen of the iPhone is just too small for me.
