This week the US' three largest wireless carriers unveiled plans aimed at people who want to upgrade their smartphones more frequently than the usual two-year period attached to device subsidies. It's all a bit complicated and there's a lot of math involved, but no matter how you look at it the savings are marginal or inexistent, as you're still paying nearly full price and have to trade-in the device when upgrading. With AT&T or Verizon you're also paying inflated service plans that fail to reflect the savings from dropping monthly subsidies.

For very frequent upgraders it might make sense, though. With that in mind today we want to know: how often do you upgrade your smartphone for the latest and greatest? Do you prefer to swallow the upfront cost of the phone for an unlocked device or commit to lengthy contracts for a chance at a more affordable flagship handset?
