Apple’s manufacturing partners have reportedly begun assembling the iPhone 5 according to a new report from Macotakara, which has a mixed track record. The report follows news from this morning that German Apple carrier partner Deutsche Telekom has already begun pre-sales of the next-generation Apple smartphone. Foxconn, which will supposedly handle roughly 85% of iPhone 5 production, and Pegatron, which has picked up a contract for the remaining 15%, are said to have ramped up assembly ahead of Apple’s official announcement of the device, which is expected as soon as next week. Citing information from an anonymous source, the report also notes that finished devices are not yet being packaged, as the release build of iOS 5 has not yet been finalized.
