Any downside of moving from grandfathered Verizon unlimited data to new Verizon Unlimited plan?

[gabester]

Looks like I would save some money - my current plan is for "unlimited" data only plus limited minutes on two phones ~$180 for two lines.

The new "Unlimited" plan has "unlimited" data (22GB before throttling), unlimited minutes, unlimited texting, and tethering for up to 10GB of data.

Has anyone else switched yet, determined that the fine print has clauses about the current rate as introductory or anything else? Are they doing bogus fees to switch to increase the costs of the first bill (line activation or other nonsense?)

Thanks!

From what I've read, the new plan is the way to go.
