Beware of wireless carriers trying to sell you on “bargains.” CNET notes that Verizon has come out with a new “share everything” data plan that costs just $20 a month but that also offers only 250MB of shared data. And of course, the $20 data plan is only part of the package since you’ll also have to pay for voice and SMS, which together bring the total cost of the plan to $60 a month.
