Sometimes an iPhone app will become unresponsive, and no matter what buttons you press or where you touch on the screen nothing happens. In this event, sometimes it helps to force quit the application.
Apple has made some changes with the iPhone OS 3.0 firmware and the iPhone 3GS release. Those with older iPhones will remember that to force quit an application you could just hold down the home button until the app exited.
Some users have found that downloaded applications have stopped working on the iPhone 3G. In addition to this bug, media such as music suddenly becomes invisible even though the files remain on the device.
There are several suggested workarounds for this issue until Apple releases a fix in September. Please refer to this article for one comprehensive solution.
We've been getting numerous reports of users, who have attempted to sync their iPhones after the latest iTunes updates (7.4.x), finding that iTunes shows space on their iPhone occupied by something specified only as 'Other'. Often, this space may be only small amounts (a few megabytes), but we have received reports of 'Other' taking up as much as 4 gigabytes.
Unfortunately, scouring available information sources and speaking with Apple hasn't led to any type of easy resolution.
