I realize most of you may use 3rd party apps to tether but for those that tether with the built-in hotspot, Verizon is still offering the unlimited 4G mobile hotspot for anyone who has a 4G phone, for an additional $30/mo. You must also be on a grandfathered unlimited plan to get it. This was originally launched last year when the Thunderbolt was first available. I thought it had expired but not so much. Again, it's for 4G phones only and not available for the share everything plan. Just thought I'd pass this along.
