Ok, we have nextel-need for industry. Switched to a bb and it changed tower on that phone to sprint which is not working where our nextel did. I don't need another cell plan but I do need away to get emails and view attachments,etc. Does anyone use AT&T's data plans w/out cellphone service. I am assuming to be able to use the gps on the BB you would need internet access not just browsing. I am so confused b/c what all uses data.
