Woah! 1.1.4!!! I don't think you've ever updated your firmware!
With firmware updates you basically improve the overall performance of the phone , any stability issues are dealt with. e.g when the iphone 3G was released there was a problem of bad reception so Apple released a new firmware to deal with the issue.
New features are also added (although so me cannot be used in Pakistan).
You can take "street view" with Google maps as an example.
The latest firmware is 2.2 and it has been jailbroken.

You can't increase or improve the speaker volume.

Unfortunately the iphone 2G has a recessed headphone jack so only the "stock" headphones can be used.
Apple has come out with a new much better set of headphones BUT with a hefty $79 price tag.
Expensive but apparently excellent sound quality (im going by what people have told me, not tried them myself).
