Hey guys, I'm finally going to upgrade my old original 2G iPhone. 
AT&T says that since I'm grandfathered, I can have an unlimited data plan for $30/month --or-- I can get the regular iPhone 4 data plans at $25 for 2 GB or $15 for 200 MB.
Currently I'm only using around 200-325MB per month, but...
Should I go with unlimited, just in case? Is there any reason to keep myself "grandfathered", or should I just let it go?
Thanks!
