I have the Blackberry Pearl and I am on a plan with two other people but I want to end my contract three months early and move to another company. How much will I pay to end my contract early?
A BlackBerry is a smartphone; assuming that is the phone you purchased under contract for your line, and your "3 months left" is accurate, the ETF would be $350 less 21 x $10 for the completed months of your contract, or $140.
