Verizon launching new unlimited prepaid plans on February 1st

According to the document, Verizon will allow users on the $80 prepaid plan to be grandfathered in, and right now the carrier is promoting a special for double the data on that plan if you sign up before January 31st. The trouble is that the old $80 plan gives users 1GB of data on a smartphone, which jumps to 2GB with the new promotion, but looks to be the same as the new $70 plan, so we're not sure why anyone would want to be grandfathered in with that old plan. 

The new plans will be $60 for unlimited talk and text, plus 500MB of data on Verizon's 3G network, or $70 for 2GB of data. Users will be able to purchase an additional 1GB of data for $20, if you go over your limit. And, if you don't keep your account funded to your plan's pricing level, you will revert to the pay-as-you-go rates.
