3:05 PM -- An ideal wireless world for T-Mobile US Inc. CMO Cole Brodman is one in which device subsidies don't exist.

That's what the Magenta chief said in a panel discussion at last week's Geekwire Summit, a statement he backed up in a blog post on Monday.

His logic is that the deep discounts carriers are required to give to subsidize a phone devalue the device, distorting the cost and creating an uneven playing field for the handset makers, retailers and carriers. "We’ve also unwittingly created a disposal marketplace for some pretty amazing products," he wrote.

T-Mobile offers Value plans in which customers pay full price for a device, but they can set up low, monthly payments to pay it off. It's essentially the same as paying off a contract, but there's no commitment and no pressure to upgrade your phone every two years. Brodman wants the entire industry to follow suit.

He writes:

Many, probably most, Americans don't realize the actual cost of the phones they're purchasing. That's why Nokia Corp. (NYSE: NOK) has always struggled here with its unlocked $800 handsets. Suddenly doing away with contracts would cause consumer backlash. But, the rising costs of data -- not to mention tiers and caps -- might make it worthwhile over the long run.

The key would be for all the wireless operators to make the move. Sprint Corp. (NYSE: S) is one carrier that probably agrees as it pays out the wazoo for each iPhone it sells, but it'd be hard to get the bigger guys with the deeper pockets -- AT&T Inc. (NYSE: T) and Verizon Wireless -- on board. (See Sprint Sees iPhone Subsidies as Necessary Evil and Sprint Talks iPhone Subsidies, LTE Devices .)

It is something to think about though. Cheaper Androids are already winning out over the iPhone in markets without carrier subsidies, and around 1 million people have forked over $629 for the new iPad before it's even out. It might be the right time to at least consider a business model change in the U.S.
