Nobody could imagine the huge success of Apple’s iPhone when AT&T and Apple starts selling them in July 2007. The release of cheaper and slimmer of 3G iphone poses big challenges to the big mobile phones makers. So far, we have seen numerous “iPhone killers”, such as Samsung Omnia and LG Dare. Sony Ericsson, in the meanwhile, is marketing this Sony Ericsson W760i phone which has some pretty nice features, such as shake control, 3G gaming with dedicated controls, and built-in MP3 music player. Do you think you will buy this Sony Ericsson W760i phone instead of 3G iPhone? I personally won’t.
