A plug icon then showed up on my i Pod so I plugged it into the mains. - Scott This was a actually a pretty common problem with the old fourth-generation i Pod.The plug icon will not go away, when I try to reset my i Pod the Apple logo comes up, I press play and then a battery with an exclamation mark comes up. Early i Pod models only charged over a 12-volt Fire Wire connection, and the fourth-generation i Pod was actually the first model to allow for both USB synchronization and charging.Unfortunately, for whatever reason Apple didn’t extend that USB power compatibility to the actual firmware update process.
Originally, this wasn’t a big problem as these i Pod models shipped with a Fire Wire-based charger that could be used to complete the restore process.
The plug icon essentially meant, “Connect your i Pod to the wall adapter” which would have been a 12-volt Fire Wire connection.
Apple has just updated the firmware for the i Phone and the i Pod touch to 2.2.1.
The list (at least for the i Pod touch) looks like it is mostly bug fixes and stability improvements, but we're still searching for a full list of all the changes.

Firmware updates are released periodically to help improve connection speed, connection reliability, motor controls, and Auto-Lock.Of course, with every i Pod released since 2005 now using USB charging only, Fire Wire cables and adapters have become much more difficult to locate.Sadly, finding a Fire Wire power source is still the only solution to completing the firmware update process.I plugged it into my PC and it was recognised and i Tunes started up.i Tunes then recommended an update for my i Pod and I had that installed.Let’s take a quick look at how to seamlessly update your i Phone or other i OS device using i Tunes.
