Customers in Germany and Britain lined up to buy the iPhone as it debuted there Friday, with Apple Inc. hoping to replicate the success that the combination cell phone, music player and Web browser has seen in the United States.

Apple hopes to sell 10 million iPhones in 2008, helped by its launch in Asia next year.

In Germany, the phone went on sale at more than 700 T-Mobile shops, including one in Cologne that opened just after midnight with some 350 customers already waiting outside.

By 5 p.m., Deutsche Telekom AG, which owns T-Mobile, said it sold more than 10,000 iPhones in Germany through its shops and online. O2, which is providing cell service for iPhones in Britain, said it would not release the number of handsets sold Friday.
