An anonymous reader writes: According to a memo leaked by MacRumors, Verizon is planning to introduce a new $20 upgrade fee starting next week. The new $20 flat rate charge will begin next Monday, April 4, and will be applied to smartphones purchased on a Device Payment financing plan, or at full retail price. The premium will also apply to those who take advantage of Apple's new iPhone Upgrade Program. Verizon cites "increasing support costs associated with customers switching their devices" as a reason for the new fees. The new fee is in addition to the existing $40 upgrade fee for customers renewing a two-year contract with a new device.
