I currently have the Samsung Fascinate and the unlimited data plan, with a 20% corporate
discount . The 2-year contract started when I bought the Fascinate in November 2010.
If I'm not mistaken, my unlimited plan is grandfathered in, even after Verizon changed the
2GB limit for data plans.
There is no 4G service in my part of the state. There won't be 4G for at least 2 years,
according to the Verizon corporate store manager. My part of the state was the second
to last to get 3G on the east coast. 
If I take Verizon's offer and accept the Samsung Droid Charge 4G as a replacement phone,
what will happento my existing unlimited 3G data plan? Can they activate the 4G phone
on a 3G data plan?
Will the 4G phone pick up 4G signal when I travel to a major city with 4G service? (nearest
city with 4G is 230 miles away)
