iphone data plan

My Iphone died last year and I just used an old Razor that I had before until the new Iphones come out. I dropped my old data plan because I can't really use the razor for anything else but voice calling. I plan on getting the new I phone 4g when it comes out this month.

My question is should I go back and get the unlimited before they cancel it on June 7th or just get the new plan?

How much data do you use a month? Can you please post it. I can't remember how much I use to use and AT&T says it is to far back to check

Thanks

Get the unlimited now while you can. If later on you find out you don't need it, you can always switch to one of the newer plans.

Regards.
