NORTHEAST U.S. -- Might be taking existing VZW Phone elsewhere

I am looking for a low cost path for:
a] retaining cellphone services;
b] not purchasing a new phone (therefore I'm wanting to unlock my DroidX2 from VZW, if possible);
c] equaling or improving my data limits. I'm presently on a Family plan.

I am about to renew in a few weeks, I am presently on VZW service with a DroidX2.
I am wondering about plan performances. With my current situation, which might not continue much longer, I have wireless access at home. I may have to terminate that service. In that instance, I would need to use my cellphone for an amount of internet data. I estimate about 1 to almost 2 Gigs per month will be a running average over the course of a year or less, and I use Linux which means I might upgrade my OS at a penalty of 900megs of data for a successful download. That means there might be months where I add up to another 1.8 Gigs to that running average. That said, I might hit nearly 4 Gigs in a month, possibly as soon as month 2 or 3 after the switch.

I hear there are some bargains for p.a.y.g., and I'd prefer prepaid for the convenience (yes, I know there is a price for the prepaid convenience, so maybe no prepaid).

Net10 seems very versatile, but I'm still very early in my research.

Anyone have any related experiences with NET10 to share?

TIA.
