Minnesota Democrat Senator Amy Klobuchar said on Monday that she will introduce a measure to prevent US cellular carriers from raising their early termination fees (ETFs) quickly. The move is a direct reaction to Verizon's decision to double ETF rates for "advanced devices" like the Droid to deter customers from exiting their service early. Klobuchar claims the rate hike has "little to no relation" to the cost of the phone and that it punishes those who depend on cellphones and have to quit for honest reasons, such as moving into regions that don't have coverage.
