Apple's iPhone finally goes on sale on China Mobile – the worlds largest carrier – this coming Friday, and ahead of this CEO Tim Cook has joined his counterpart from Apple's latest carrier partner for a small media briefing. Pre-orders have been going extremely well, and Cook is said to be "incredible optimistic" as reports the Wall Street Journal:

Apple Chief Executive Tim Cook said he is "incredibly optimistic" about the outcome of the cooperation with the Chinese carrier.

"We've gotten to know each other....today is a beginning, and I think there are lots more things our companies can do together in the future," Mr. Cook said.

"As of this weekend we will be selling iPhones in more than 3,000 additional locations. China Mobile already has a reach to many cities that Apple does not have a reach to."

The partnership between Apple and China Mobile is said to extend beyond handsets, and into a broad cooperation between the two companies.
