this thread just caught my eye and thought i would respond,a while back i got tired of being throttle so i switch from unlimited data to 200 mb in which later i found out that the 200 mb plan was 4g...well i don't know exactly if it's really 4g or not but i can say that my phone would go from 3g to h...and i even called tmobile to reference to the plan and different reps all told me that the 200 mb was 4g...and incase some is wondering,i went out and got a wifi mobile hotspot device...
