Sprint CFO Joe Euteneuer at a Barclays Capital conference speech revealed that his company's iPhone deal would let it carry an LTE model at any given time. He wouldn't be drawn into confirming any timing, but he told Dow Jones and others that the deal was like that for other US carriers and didn't require a certain minimum of LTE coverage. Sprint's LTE will switch on mid-year with just six cities, which some had taken as a sign that Apple might pass on Sprint in favor of the more complete AT&T and Verizon networks.
