Apple updated the software that runs its iPhones on Friday in hopes of decreasing dropped calls, improving battery life and cutting the time it takes to synchronize the device with a computer.
Shortly after Apple made the new software available on its iTunes online service, some users offered positive feedback on Internet forums, saying it appeared the device was getting faster at handling key tasks. In contrast, an August update that was supposed to improve the iPhones’ connectivity to high-speed data networks drew mainly negative responses claiming it didn’t work.
