If you NEED 3G for either fast retrieving of the emails (as the browser is mediocre) or for video calling, this is the only Ultra slim Samsung with it. But if not, the U600 will offer you sexier design and quad-band GSM that can be used anywhere a network of this type is present. If you don’t need lots of memory and don’t plan to use the phone as a music player, better check the U100 which comes at half the thickness.
