According to a tipster for Berry Scoop who has been "dead on" in the past, Verizon is about to offer a prepaid plan for certain BlackBerry devices. The plan is expected to start sometime in the next 90 days and will add $35 a month onto the cost of the voice plan. Unfortunately, we don't know which handsets will be included. As we reported yesterday
, Boost Mobile has recently started a prepaid plan for the BlackBerry Curve with the phone costing $249 and a package of $60 per month covering unlimited voice and data.
