As nifty as your iPhone may be, the handset is never perfect and glitches can emerge from time to time.

Fortunately, methods exist to get around these errors.

The guys at Macworld have posted an excerpt clip from a recently released iPhone guide describing how to get around common freezes, hangs and delays present in the iPhone. Take a gander:

To unfreeze an iPhone press and hold down the Home key for about six seconds. If this works, you are returned to the Home screen, with (hopefully) everything working again. If a force-quit fails to unfreeze the application, try further actions as described ahead in this section (begin with Restart, below).

Handle crashes:
When you’re working with an iPhone application or widget, the iPhone may suddenly toss you back to the Home screen. When you return to the program you were using, you may further find that some of your recent changes have been lost. For example, a Web page that you had closed may now be back. When this occurs, it means the iPhone software has crashed.

After being dumped back Home, you should simply return to what you were doing and hope the crash does not recur. If the same crash does happen again (and sometimes again and again), try restarting your iPhone (described next). This often helps because many crashes are caused by a combination of events that won’t reoccur in exactly the same way after a restart.
