Nothing to worry about here guys. All networks have a 'limit', but its only to act as a guide and a deterent against massive streaming/ modem usage/ p2p stuff.

I regularly go over my orange 500mb, by a few gigs normally, and never had a call. My collegue on voda and tmob absolutely hammers his, using rapidshare ect, and again, no issues.

Infact, in 4 years of CPW, I have never had a customer come in with charges for extra usage, other then usb dongles, which DO charge if you go over (tmob aside)

In this smart phone and facebook era, to cap and charge customers for net overuse would be network suicide, as so many hammer iphones, android and winmo devices. Dont worry about it. The worst that could happen for constant crazy overuse is a text/letter warning that they may have to throttle the speed if you don't calm down on it. Never seen it happen, so I really wouldn't worry about it.
