Thank you for your reply.
I think I need a lawyer to interpret the contract. There is literally a full page of small writing and actually nothing clear about what is and what is not "data". In fact it doesn't even mention the 500 MB limit.
The only BIS/data related sentence is "Public mail (BIS) Synchronization of up to 10 accounts public email in BlackBerry hardware (Hotmail, Yahoo, Gmail, etc.)" (translated from spanish).
Is there a way to tell what kind of data an app is using, Blackberry or other? Or should I investigate in forums? I mean i.e. how do you know Maps is BlackBerry data?
Also regarding the proxy thing. If I go to What Is My IP Address - Shows Your IP Address
from my BlackBerry I see this: 220.127.116.11
Possible Proxy Detected:
Which to me it means that the data is being proxied through server in the BlackBerry network... I don't know what it means for me and my cryptic contract though.
Sorry, this is all too much fun!
