Traveling 10months out of a year I'm currently with tmo on their intl BB plan. But with the recent changes to their intl email plan and data usage, its making my rethink switching service.
Any ideas?

There are 4 of us on the family plan
father uses a little bit of data but lots of calling to mainly a few phone numbers and same mobile operator (wife)
wife same as father
brother uses a BB but wants to get the iphone
I dont care but i need to get email all the time and some data and I roam all the time. No calls though as I use skype or something similar

I think ATT has a good data package for small business - 60 or 65/month for the iphone with unlimited data, but how about the other companies?
Any recommendations
