Summary: Its a BlackBerry what else can I say. Just be aware Sprint will tell you that you cant activate the phone. But what I found is that you can swap the phone with an active number no problems , I had to buy cheap preowned phones and swap them to blackberrys.
Summary: So I bought the phone unlocked to use with other service provider, within and outside the US. However all the tools of the phone can't be utilized. The Email Setup does not work after being unlocked and it seems there's no way of getting around that. The built in navigation also tends to not work as well..
