T-Mobile launched the G-Phone today which at first glance seems to want to be both a Blackberry and an iPhone with both touch screen and slide keyboard; at the moment the T-Mobile version only connects up with Gmail and in fact you need to have a Gmail account to use the G-phone. The key to this phones success will be how apps are created and distributed.
Will be interesting to see how the mobile market evolves with these new types of hardware!
