Not exactly a huge surprise here, but it looks like Verizon will be doing everything it can to pair folks with a new iPhone 4 when it launches on the carrier next month, even if they've just purchased a new phone on Verizon or another carrier. During an investor meeting this week, Verizon CFO Fran Shammo revealed that the carrier will be using its existing trade-in program (which launched in October) to lure would-be customers, with a Verizon rep further detailing that it will be "more actively" promoting the plan in the lead up to the iPhone 4 launch -- under that program, a 16GB iPhone 4 from AT&T will net you a $212 credit. In addition to that, Verizon is also rolling out a new "Special Upgrade Offer" that will let existing customers trade in a phone they've recently purchased for a Visa debit card ($200 for a smartphone trade-in, or $75 for a feature phone). Only those that have purchased a phone between November 26th, 2010 and January 10th, 2011 will be eligible, though, and you won't exactly get that cash right away -- you'll first have to first buy and activate your iPhone 4 at the full retail price, send in your trade-in phone within 30 days of activation, and then wait four to six weeks to receive the debit card.
