My brother has the voyager, I personally have not had much experience with either phones, but I do believe the iphone has more capabilities, when my brother gets on the internet it's the same as on my samsung alias, so I do believe the iphone is more powerful. However the advantage witht he voyager is the fact that it has the keyboard, the iphone has a touch keyboard which idk how much I personally would like that, so, it's pretty much whatever you think and how much you are willing to pay. Also, a neat feature that I'm not sure if the iphone has it or not, but there is live tv on the voyager. It has a little antenna and everything.
