If you recall, T-Mobile made a big deal last December about the fact that they had eliminated their annoying $18 "handset upgrade fee." Well, several users tell us it's back from the dead, one user noticing the re-established fee when he went to upgrade his sister's line. A slew of other carriers often jam consumers with a nonsensical handset upgrade fee, though there's usually ways around it if you jump through whatever hoops they've established (upgrading online, in person, through a big box retailer, or via carrier pigeon on the second Monday of each month). Such nonsensical fees are part of the cost of doing business, but are broken out below the line to milk more revenue from customers while keeping the advertised price the same.
