#2. AT&T
Coolest product. Lousiest service.
The nation's No. 2 wireless carrier has long been a thorn in the side of Apple lovers. But customers' ire towards Ma Bell has moved beyond the spotty 3G service and dropped calls that have made AT&T the butt of late-night jokes.In early June, AT&T was the first U.S. mobile provider to do away with unlimited data pricing, threatening to raise some iPhone and iPad customers' monthly bills. A week later, a security hole in AT&T's website allowed hackers to access more than 100,000 e-mail addresses of iPad 3G customers. AT&T fixed the problem, but took an entire week before the company chose to notify the affected subscribers.
If all that wasn't bad enough, AT&T servers then couldn't handle the barrage of pre-orders for the iPhone 4. Though Apple apologized for the incident, AT&T never did, simply e-mailing many of its customers who were able to pre-order, notifying them that their new iPhones would arrive late.
