I was under the impression that it only worked if you were in a 4G area and I was on the phone while tethered to my laptop. I pressed the refresh button not thinking that I was tethered to my phone and I was expecting to get a "page cannot be displayed". Nope, it refreshed. I was kinda shocked at first, so then I downloaded an app from the market while on the phone. Sure enough, it downloaded. Also, the store that I purchased my TB from said that Verizon is running a hotspot promotion through mid-April for unlimited data $20/month. Anyone else heard this? If this is the case, I'm signing up and cancelling internet at home, cuz Im only there a week of the month.
