Apple is gearing up for a big bump in sales of the next generation iPhone, if new production plans are any guide.

The plans show the faster iPhone will be rolling off the assembly line this summer. The initial order calls for 11 million iPhones to be built this year, with that total split between the existing 2.5G phone and the upgraded 3G phone, according to people familiar with the plan. **Prototype

Apple appears to be targetting a June introduction of the 3G version of the phone, roughly a year after the original iPhone's debut. And similar to last year, Apple seems to be scheduling a limited initial supply to be followed by more phones in the fall quarter. The new phone will operate on AT&T's faster network giving a big speed boost to mobile Internet users. The new phone will also be packed with more features including GPS navigation. Apple will clearly have a big price tag on the new phone, and observers speculate that the older version - which fetches $500 for the larger memory model - will likely get another price cut
