Exactly what the jailbreak is for. You want some locked features? Jailbreak. Even more reason why it is the best phone out. Of course I want to see an LED screen and some enhancements but front-facing camera, slide down keyboard, extrs buttons? For what? My goodness.
iPhone 3GS running 3.1 since the 25th is the greatest phone out! The iPhone is finally complete, any wish list made now will just be add ons or a sought for innovation, we are currently where cellphones haven't gone before. Perfect? Close to it! In comparison to the standard that a typical cellphone/smartphone would have. Room for growth and innovation? Sure! There is always room for inovation and new technology. So now, all we expect are enhancements to what's currently great! It will be great to get some of the functionality seen in JB phones but to me those are just customizations that don't take away from the iPhones core functionality. Long and short of it is the iPhones the best phone out there, developers, 3rd party accessories makers, users, other phone companies and you all know it!
