I'm seeing this a lot lately on forums and I'm still kind of confused. What does the 3G Mobile HotSpot app do on my DX? Is it just a tethering app? For instance, I can connect my laptop to Verizons 3G network and access the internet? I'm too sure what the app does? I saw the TBH hack for it but I thought tethering was free? What's the difference between 3G HotSpot and say Wireless Tether for Root Users in the Market? There are some many apps, PDANET, etc.
