Hey, guys. Right now I'm thinking of getting a mount for my iPhone for my bike. Hoping to use it for GPS as a temp thing till I can get a new real-GPS. Does anyone have experience with using Maps for a long time (always open)? My brightness is "medium" and I plan to have 3G/Location on. I won't be listening to music. And I don't have Push notifications. Do you guys use Maps to navigate through the city without 3G? I'm on a motorcycle so I would be in fast traffic so I guess 3G would be better? I'm sure the battery would last longer than 2 hours, right? at 100%?
