China Mobile has begun accepting preorders for the so-called “iPhone 6,” a week before Apple itself is expected to officially announce its next-generation smartphone.

According to China Daily (via MacRumors), the largest mobile carrier in the world has launched an online preorder campaign for the highly anticipated device. Interestingly, the campaign all but confirms that the iPhone 6 is set to come in 4.7-inch and 5.5-inch versions, as prospective buyers are prompted to choose between the two models.

China Mobile’s preorder program is available in the Chinese capital of Beijing only. Be that as it may, more than 33,000 preorders have already been placed for the iPhone 6.

One of China Daily’s sources claims that the device may begin shipping to customers as early as the middle of the month.

Online preorders for the iPhone 6 have been offered in China by unofficial sellers since as early as last July, primarily through Taobao, the largest consumer-to-consumer e-commerce site in the country.

Apple is expected to unveil the iPhone 6 at its special media event on Tuesday, Sept. 9. In addition to larger screens, both rumored models of the iPhone 6 are likely to feature thinner profiles and Apple’s faster “A8″ processors, among other improvements.
