When the iPhone 5 comes out this summer, I anticipate a lot more people making the switch. I know of a few people who want to switch to Verizon, but are waiting cuz they know the next iPhone is on the horizon (similarly, I have friends on AT&T who want to stay with AT&T, but are also waiting til summer to upgrade). Not only do they not want their phone to be obsolete in 5 months, but the new iPhone is expected to have LTE.
