Here's another reason to consider going the unlocked route with the Nexus One, in addition to having the AT&T (non-3G) and international GSM option. As a number of people have noticed, Google's got its own Early Termination Fee (ETF) equivalent, here called the Equipment Recovery Fee, in the terms of sale, to the tune of $350 if you cancel within the first 120 days. Sound familiar? It's because we saw it in a leak just before the new year. Here's the kicker, though: this is in addition to any fees imposed by the carrier -- not necessarily a problem on its own, but we just glanced at T-Mobile's terms of sale, and sure enough, there's an associated ETF up to $200. If we're reading this right, Nexus One owners who decide to end their service after the 14-day trial period is over but before four months have passed will be hit with upwards of $550 in fees -- more than if you bought the phone outright from the start, especially when you factor in the upfront $180. There hasn't been enough time for someone to tempt fate, but who knows -- come January 20th when early adopters' trial period ends, there might be some interesting stories abound.
