ok..is it safe to do this? do a wireless tether on the ps3 online? will vzw ding me for this? i'm guessing this is a lot of data? my bro-in-law doesn't have high speed internet at home (no access for dsl). so instead of paying for $40/mo on cable internet, i was thinking of just having him do the data plan for verizon (rooted droid of course). is this wise?
