In plain English, you are fine to update your iPhone without any problems. Just hook up your iPhone to your computer, and update through iTunes.
Jailbreaking is the essentially hacking the software of of your iDevice to install a third-party application called Cydia, WHICH IS AN UNOFFICIAL APPLE UNAPPROVED APP STORE" that has the ability to fully unlock capabilities of your iPhone, such as customing, themes, unofficial games apps, cracked apps, etc without Apple's permission or consent. Although legal from the DMCA ruling in the U.S., it is unnecessary to jailbreak your iPhone if you do not have the need to, or if you are new with your iPhone.
I think the battery issue was supposed to have been rectified on the last update, although I find the battery life on my iPod Touch quite pathetic. Sure hope my iPad 2 coming will do a whole lot better.
How bad could the battery life be on the iPod Touch? Anyways, do you use it a lot? Have you tried specific settings to minimize the amount of battery being used (Wi-Fi turned off when not needed, bluetooth off, push e-mail off, etc)?
