When Verizon Wireless began offering the iPhone, they reduced their return time for devices to 14 days, AT&T was more generous in the amount of time given to buyers in its return policy until recently.
AT&T has updated its device return policy, limiting the return period of 14 days to return a device for any reason or cancel service without paying an early termination fee (ETF).
Early termination fees have been get more and more expensive while data plans have become limited to usage based pricing.
AT&T customers have been receiving notices. The change to 14 days began on October 7.
