I have a Blackberry Storm 9550 (Storm 2)....my data package is "Unlimited Email & Web for BlackBerry (personal email)," which I pay $29.99 per month for.....
With this data package, can you guarantee me that I will not get any fees for tethering from Verizon?



We can't guarantee you won't be charged, I am a Verizon customer and I have the same plan and I have not been charged any additional fees for using Tether.
There is a long thread on this subject on the forum, I'm mobile right now and can't provide a link but it explains users experiences with Tether and Verizon.
