Do you own an iPhone 4S? If so, you and tens of millions of others like yourself in the United States and abroad won't qualify for a fully subsidized upgrade this fall. Blame it on the disparity between yearly iPhone cycles and carriers' policy of locking smartphone buyers with two-year contracts.
Apple's phone is enjoying stellar sales, moving 37.1 million units last holiday and 35.1 million last quarter, thanks partially to last summer's pent up demand.
The question is, will iPhone 4S owners - now locked into wireless service contracts and not eligible for fully subsidized upgrades - be willing to pay extra to obtain an early iPhone 5 upgrade this fall?
