Apple (and many other companies) don't announce updates.
If Apple did announce an update, their PR office would announce it first, so the best place to hear about it first is Apple.com's hotnews RSS feed.
Personally, I just click on the check for updates button in iTunes in the morning before I undock and head to work.

Mine iPhone doesn't appear to have the glowy battery when fully charged. I don't care of the battery graphic looks like a Zune... my iPhone charges, and the battery life is great, so I'm ok with a non-glowing 100% full green battery graphic.

Sometimes, as in the reported email Word doc answer, and the reported update next week answer, people make mistakes. You're dealing with a phone tech, probably an overworked phone tech, not the head of Apple PR, and with anything that involves people, you sometimes don't get the right answer.
The Apple staff didn't know anything about the iPhone that you didn't, and probably less since they were all busy working overtime during the release and unable to scour the internet for news.
So, if someone tells you something, ask them where you can find it from Apple. Apple is busily creating support files on the iPhone with all the official answers than they are currently giving. If you're new to Apple products, start with their support site:
http://www.apple.com/support/iphone/
If it's not there, then they haven't told your local Apple employees about it either.

As for not accepting a return for the battery graphic issue... Apple has in the past, and it seems to be the case with the iPhone, accepted some 'interesting' replacements not covered under the 1 yr warrantee when they first release a brand new product. After the initial round of figuring out what is and isn't a real warrantee issue, they seem to stop giving replacements for questionable reasons. If you can't live without the glow, you're probably going to find that it's about the time that they'll take a completely working iPhone back for the restocking fee... after all, they need 17,000 working iPhones to give to their employees by the end of the month.
My guess is, they're starting to fill most of those numbers with "non-glowing battery" returns, and so don't need you to give them your perfectly working phone back!
