USA Today reports that early iPhone adopters are overwhelmingly happy with their iPhones.

In one of the first such studies, 90% of 200 owners said they were "extremely" or "very" satisfied with their phone. And 85% said they are "extremely" or "very" likely to recommend the device to others, says the online survey conducted and paid for by market researcher Interpret of Santa Monica, Calif. The firm surveyed 1,000 cellphone users July 6-10.

Of course, early adopters are a special population and may not reflect the satisfaction of later consumers as a whole. Some other interesting statistics that came from the studies are included:

• 51% of buyers were switching to AT&T from another carrier
• 35% of carrier switchers paid an early termination fee (avg $167) to switch
• 3 of 10 were first-time Apple customers.
• for 4 of 10, the iPhone was their first iPod
• New iPhone owners expected to pay about $35 more a month than their previous cellphone.

Meanwhile, Forbes publishes a report that Telefonica SA's O2 mobile phone unit has reached an agreement to become the exclusive network partner for Apple's iPhone in the UK. Sales are reported to begin "shortly". Vodafone had reportedly been a front runner in negotiations but in the end felt that the commercial terms were not viable.
