It has now been 2 years that Apple and AT&T are teaming up to offer and support the iPhone on the US market. The carrier is even working hard to get this exclusive partnership extended till 2010. The honey moon between both companies might experience its first clouds as 4 senators have sent a letter to the Vice-president of the FFC (Federal Communications Commission) to request an investigation to be opened about exclusive partnerships, taking AT&T-Apple as an example, but willing to extend it further.
