Is this referring to duplicate features offered via AT&T's network such as SMS and Voicemail? Or is it referring to duplicate software programs that come pre-installed on the iphone such as the browser and ipod app etc? If it is the latter than this is an unsettling precedence. Why would Apple stifle any program that does something an Apple program does? That would be like Windows banning firefox from being installed because it does something the pre-installed IE does. Different browsers should be available. Why did Apple reject Opera? Doesn't seem to make much sense.
