Memos suggest that activations will be completed entirely in store, though not whether they will still be divided into a rumored two-step process. The insistence on control is expected to produce heavy demands on AT&T staff, to the extent that the company is calling for extra part-time help simply to run 3Gs from storage to clerks, "to facilitate unbricking." The company is further pressuring workers to take extra four- to seven-hour shifts in other unorthodox roles for launch weekend, such as Greeter, Crowd Manager or Floor Coordinator. Crowd Managers are expected to setup line barriers, and "coordinate efforts with [the] Line Manager to ensure customers are iReady;" Floor Coordinators are responsible for ensuring reasonable occupancy, as well as a lack of line cheating. Network engineers, meanwhile, are said to be making continual refinements to AT&T's 3G network, using information gleaned from past Fine EDGE enhancements. This includes extra radio capacity, earlier triggering of additional resources, and a larger number of T1 lines. The company is also attempting to speed up overlay work that was originally scheduled for 2009.
