　　iPhone squeezes phone carriers' margins 　　
　　NEW YORK (Reuters) - Profits at the three largest U.S. phone carriers are being squeezed by steep discounts on advanced cell phones, triggered by AT&T Inc's hefty subsidy for the iPhone.
　　AT&T, Verizon Communications Inc and Sprint Nextel Corp are expected to show a drop in wireless profit margins when they report third-quarter results in coming weeks, also feeling the pinch from consumers holding off on buying add-on services like data to lower their phone bills in the weak economy.
　　Wireless carriers have always shouldered part of a phone's cost to persuade customers to sign longer-term contracts, but U.S. market leader AT&T lowered the bar when it helped Apple Inc launch the latest iPhone for only $200 on July 11.
　　This forced Verizon Wireless, AT&T's biggest rival, and Sprint, the No. 3 U.S. mobile service, to follow suit with higher subsidies on their advanced phones, analysts said. While that helps boost service revenue in the longer term, it hurts near-term profits.
　　"The derivative effect is lower profitability in wireless for all the carriers," said UBS analyst John Hodulik, adding that the iPhone is selling faster than he expected, which is actually bad for AT&T's profitability in the short term.
