iPhone 4 Data Use Question

[04scoobysti]

I picked up the iphone 4 last month at Rogers.
They had a promo on (I think its still until the end of the month) with their data package its was $25/ 500mb or $30 for 6GB.
Needless to say i went with the 6GB.
I dont think i will ever come close to putting more than a small dent in it, but hey its there incase I do.

It can be one hell of a bill when you tether it to a pc and they start charging you per KB, like this poor guy.
