I'm on O2.
Only just got my contract today. O2 customer service phoned me to see if I was happy with my phone etc - boy did they open a can of worms. I started to ask him about "if i was using a different browser, would the traffic be covered by my blackberry unlimited plan. What if I was accessing my server, would that be covered..." etc.
The poor guy spent the whole afternoon phoning around the different O2 departments to try and find out, and got no where. He's allowed me to run all the apps I want on the phone for the next 7 days - if at the end of it I'm being charged for extra data he's going to cancel the charges. Not the best solution but it has hope.
I'm going to be running on my Curve (O2 unlimited data plan)
Google Maps - linked to my GPS on the curve.
Can any one tell me the application that measures how much data is transferred?
(found it - MiniMoni - Traffic monitor for BlackBerry
