The official answer is no. There are differences in both the charging and syncing cords between the iPhone and the iPod.
This means that if you use an old iPod cord with your phone, or the other way round, it could damage your battery due to the variance in electrical loads that they can carry.
It can also mess up your syncing.
That said, a lot of people do use the same charger for both gadgets without any problems. Why this is possible is unclear - perhaps it depends on the year the charger was made, or where it was made. A slight difference between products may produce a different result.
The quickest way to charge your device is to connect it to a power outlet using the USB cable that came with it and a USB power adapter. It's as simple as that.
You can also connect it to a USB port on your computer using the USB cable that came with the device. Don't run it through the keyboard though as it won't work. Your computer must be turned on and not in sleep or standby mode. For the quickest charge while connected to a computer, remove all USB devices except the keyboard and mouse.
If you're using a laptop, make sure it is plugged in to power and that lid is open. If you close it the computer may go in to stand-by mode and the iPod or iPhone won't charge.
Also, if you charge the battery while syncing it might take longer to charge.
