Greetings used,
There really isn't anything too difficult with wifi-teathering. There are a few apps available that allow you to use this function, without the b.s $30 fee Verizon wants. That being said, beware that Verizon has begun to throttle connections that they deem "over-the-norm (2-GIG), so if you start pulling large numbers of band width prepare to face the consequences. I'm speaking from a unlimited account use viewpoint, if your on a Tiered service, then that 2-Gig number doesn't mean anything, as you will be bound by the amount of service you have on your account. Overages on a tiered service can get expensive quickly.
I think a couple are...
1.Barncle
2.Pdanet
There are others available on the market.
Mobile hot spots are easy to use.
1. Start the app
2. Name your hotspot
3. Assign your wanted level of protection...IE.. WEP,WPA so forth.
4. Assign password
5. Turn on hot spot.
6. On your Ipad, turn on wifi and it should see your hot spot that you just created.
6. Connect to said hot spot.
7.Enjoy
