iMore previously learned that Apple was targeting an August time frame for the next-generation iPhone 5s, and while that may or may not include more recently rumored software scheduling issues, it does sound like the general time frame is still accurate enough for Foxconn to start ramping up for production. Lorraine Luk of the Wall Street Journal writes:
[Foxconn] said Monday it has added about 10,000 assembly-line workers per week in Zhengzhou, its major production facility for iPhones, since the last week of March.
"We have been very busy recently as we will start mass-producing the new iPhone soon," said a Zhengzhou-based executive who has direct knowledge of production plans.
If Apple sticks to its 2009 and 2011 pattern of keeping the same casing two years in a row and releasing an S-class update, then presumably it'll be an easier ramp up than last year where the manufacturing technology needed to produce the insanely redesigned iPhone 5 led to the usual transitional hiccups and supply constraints.
To date, every new iPhone has shipped with a new version of iOS, and the iPhone 4S shipped with iCloud. That coupling makes for greater product impact, but also greater dependency.
Hopefully, if hardware is ramping up, that's a sign everything else is also starting to line back up.
