Apple’s struggling to crank out enough iPhone 3G handsets to meet supply. They’re in such high demand, the company’s on track to shift more than 40 million of the touchscreen mobiles in its first year alone.

That’s almost 7 times the amount it shifted of the first generation iPhone, but with demand outstripping supply, reports suggest Apple’s pushing its Far Eastern manufacturers to their full capacity.

According to TechCrunch, Apple’s manufacturing partner, Foxconn, is churning out iPhone 3Gs at the rate of 800,000 per week. But there could be trouble ahead, as that number is reportedly “above current full capacity.” TechCrunch says that if it continues, there could be quality control issues around the corner.

Issues like cracking cases? Yes. We’ve already seen those.
