I had Boost Mobile a year or two ago. The service went out for a couple of days and it was a big ho-hum for them, they never explained anything at all... I got a Galaxy S 3G phone and unlimited data from T-Mobile this year. You dl an app and connect the charging cable to your computer USB and you have internet.
There are a couple of good things about T-Mobile. The unlimited data's only caveat is that after a certain amount of data they throttle back the bandwidth. If I was playing movies a lot it would get throttled back but otherwise I'll never hit that limit. 3G is plenty for my intraday trades, not high speed at all... T-Mobile can roll out their 4G network a lot easier then the rest, they don't have to make any hardware changes to upgrade it, just some techs have to install some firmware at the cell sites and you are in 4G zone...
