iPhone 4 Data Use Question

[saltcreep]

Kind of a loaded question. I have a 3G and find that my minimal data plan is sufficient. I don't browse too much as I find I can wait to get home. Your phone will switch to networks that are available.

You will find where there are free wifi networks or open networks if you need. If you travel outside Canada, be careful of your data plan and it's limits. It can get rather costly even just with email. Set your phone to manual for the data push so you use it only when you want.
