The iPhone 3G is en route and wireless carrier AT&T has sent a variety of memos to its employees detailing proprietary measures to take including the launch of an iPhone 3G unbricking tool, ongoing 3G network upgrades/optimizations, regional ad campaigns and available jobs for part time crowd control, inventory runners and floor coordinators.

According to AppleInsider, a memo released last week stated that AT&T retail locations would have their desktop computers updated with a program "for the iTunes utility that will be used for unbricking iPhone 3G devices during the activation process. Per recent reports, employees were asked not to use the partial iTunes software until launch day, but were told that they "WILL need this icon for iPhone 3G launch on July 11th.

A leaked set of instructions supports expectations that, in the case of unit sales at an AT&T retail location, each iPhone 3G handset will need to be unboxed and fully activated within the store. Via a second memo, AT&T put out a call for additional part time staffers to work the launch weekend, the memo listing positions such as a back office manager and inventory runner whose duties would include bringing iPhone 3G units from the inventory room to retail sales consultants and then helping to unbox them in order "to facilitate unbricking."

"Although we cannot predict the number of customers who will visit our stores the weekend of July 11 - 13, we want to be prepared for crowds," AT&T's vice president and general manager for the New England region told staffers in that memo. The memo then asked that employees consider taking at least one four to seven hour shift during the weekend, as additional staff will be required to fulfill the duties of the Crowd Manager, Greeter, and Floor Coordinator.

In addition to in-store changes being made, additional memos indicate that AT&T's network engineers are making optimizations to the 3G network including "implementing improved design metrics, some of which were lessons learned from the previous 'Fine EDGE' program:

-Identify and add radio capacity where needed.

-Provide an extra carrier, enhancing capacity even more with an 850 overlay.

-Performance triggers (for additional resources) designed to go earlier.

-Escalate additional overlay work (2009) for possible 2008 future expansion.

-Address core network; sized to handle additional T1 now and adding capacity as triggers dictate.

-Modify system parameters to maximize resource efficiencies."

Finally, the company indicated that over the next few months, it will launch a series of local/regional advertising campaigns on billboards, bus wraps, radio and online.
