This may come as no surprise to iPhone owners: AT&T ranks last out of the four major service carriers when it comes to customer satisfaction. Consumer Reports surveyed 50,000 wireless subscribers in 26 cities for the annual report.

Analyst: T-Mobile iPhone in 2010
Speculation has been rampant over a Verizon Wireless iPhone, however a simpler path for Apple to expand its iPhone market would be to offer the device to T-Mobile. Doug Reid, an analyst at Thomas Weisel, sees this move as a logical step.
Apple already offers the iPhone through Germany's T-Mobile unit (T-Mobile is owned by Deutsche Telekom). The carrier has compatible wireless technology to AT&T and wouldn't require any hardware changes to the iPhone, unlike any move to Verizon Wireless.
iPhone 3G Inventory Shrinking at AT&T, Vodafone
Vodafone Australia has officially been notified by its distributor of the iPhone 3G that the 16GB model is an EOL (end of life) product. Only a few weeks' supply is left and the model will be discontinued when these are sold.
Further signs point to the impending release of a next generation iPhone, possibly by July 17th. According to sources who have contacted the company, AT&T is drawing down current iPhone model inventories and has no plans to restock.
AT&T Considers Drop in iPhone 3.0 Plan Pricing
In a move to preserve the exclusive relationship with Apple and increase iPhone sales, AT&T may be considering changes to iPhone data plan pricing with the introduction of the next generation device. A typical two-year contract would see a price decrease of $10 per month, bringing the cost back to what original iPhone users signed up for in 2007.

Market research has shown that the high monthly cost associated with iPhone contracts may steer some users away from purchasing the device. The minimum cost over the required two-year contract amounts to over $1700 not including text messaging, taxes and fees.
When will the iPhone be available on the Verizon network?
UPDATE: 01/04/2010 - Analysts are reporting that Apple is in negotations with Verizon regarding pricing of a CDMA iPhone. These reports are, as of yet, unconfirmed.
Apple has an exclusive deal with AT&T to provide service for iPhones through 2010. AT&T is trying to extend this arrangement through 2011.
When will the iPhone be available for other networks?
Apple and AT&T (formerly Cingular) have signed a five year exclusivity agreement.
If you're on another American carrier, you'll have to wait for an unlocked version of the IPhone to come along, or wait 5 years.
The iPhone will be available for other networks in Europe starting Q4 2007.
Will the iPhone work in Europe, Asia, etc?
Yes, the iPhone will work overseas, and not just in Europe and Asia. The iPhone is a GSM (Global System for Mobile communication) phone. GSM, which uses narrowband TDMA, was first introduced as a standard in 1991 and is now in place in over 100 countries.
Access to receive and place calls from outside the United States will require additional services from AT&T/Cingular, which you will need to arrange with them before your phone will operate in such a fashion, but the phone is perfectly capable for worldwide use.
Will the iPhone support Cingular's 3G network?
Up until this point there's been little reason to believe that the iPhone would support Cingular's network. Why Apple and Cingular would release a next generation device that was a generation behind in wireless connectivity has left some people scratching their heads. Recently, rumors have started circulating that the iPhone may surprise us again. The New York Times recently reported:
