I'm currently on a Fido plan with no data. I turned data off from the Iphone setting but as well using BossPrefs.

If somehow data is getting through will it show up on the Setting> General> Usage> and then under Cellular Network Data?

Are their any other measures i can do to make sure data and edge is blocked off?

^Yes, it should and there is a method in which you SSH into the phone and delete a file to kill EDGE; search around here and you should be able to find it...
