In the latest bit of “Oh yeah, me too” marketing, it seems like the top 3 mobile carriers and an MVNO all have (or will have soon) flat fee plans that have unlimited voice, messaging , and data. As a nice geture of inclusivity for smartphones, apparently the ATT plan includes iPhone users. (No word on the Blackberry crowd, yet)

Cool stuff. Soon enough, tethering or card access will join. Hooray!

ATT Plans (unlimited will be up on 2/22, I think)
Verizon Plans
Sprint Plans
Helio Plans
and T-Mo is in the game, too!

As a side note, Sprint plans seem to be limited to certain markets.

This is good stuff. Look for these prices to compress even further in 2009.
