So i have m 3gs 2 years now, and since i dont need something better (it runs iOS, thats enough to have the perfect phone), i wanna buy a keyboard extension for my iphone. A little search brought up these 2: http://www.google.gr/m/url?client=s...twIwAQ&usg=AFQjCNHeKCepbBp0YmkRKWXFsnzNxVya9w And http://gadgetsmarket.com/iphone-3gs-4g-case-flip-keyboard/. I wouldnt buy the second one because of the rotating keyboard (i want a slider). The first one seems nice but i have a few questions. Because its connected with bluetooth, ill lose a lot of battery life. Does bluetooth turn off when the iphone is sleeping? Is there another slide keyboard for the 3gs , which connects with the port instead of bluetooth? Or maybe a case with battery and keyboard(not likely)? Sent from my iphone.
