I know this could PROBABLY go into the Sprint forum...but as I am a 3V0 owner much like all of you and I needed my MSL to change something here is a very quick and efficient way to get it short of just asking Sprint for it. I've done this with 3 different 3V0s now. Call up Sprint, tech support, your 3G speeds are dog slow (15kB/s up and down). Tried it in a couple of cities no luck. When they have you dial ##3282# (##data#) you will get your MSL code. Worked on 3 different phones and took less than a minute to get it on each. Just sayin'
