Per BGR, it looks like T-Mobile is going to make some changes to data and messaging plans that might not fly well with their customers. Starting sometime in June, data plans will now be required for all smartphone-type devices (excludes Blackberry Pearl, Pearl Flip & Samsung Behold, Memoir). Pretty big deal if you don't have a need for a data plan or if you're always surrounded by Wi-Fi hotspots you never use data. Secondly, the unlimited family messaging plan is going up from $19.95 to $24.99.

These changes are definitely harder to swallow than those before, are they deal breakers for any of you guys?
