This phone has all but InfraRed Port. This phone has some software limitations that it cannot open some applications for some software failure. You could not keep a tab of open applications. The best part is the design of keys, you can stare at them for days wondering how they came up with such lines of flow. Holding this phone makes me feel like Howard Roark. In all this phone is better than many others but the price tag is much too high for its relativeness. I suggest not buy this phone but go for revisions that are better and low priced. Battery back up is also bad since most of the power is used up while using camera or playing games(mind you there are no games supplied by default a big minus for many) and needs recharging in about 2-3 hours of continuous use. Better go for 6600 since it has all the features but some low pixel.
