iPhone batteries have Lithium Polymer (and Lithium Ion in older models) which require to be totally discharged to the point of the phone not capable of being turned on. This realigns the electrons in the battery and makes the battery work properly. If you don't do this every (according to Apple) 10 charges it'll ruin your battery.
To the best of my knowledge, running the battery down to zero helps to syncronize the battery meter. I'm not sure if it does anything for the actual battery though, as most rechargeable lithium batteries can't be discharged below 3.6V without damage. I could be totally wrong, but I would imagine iPhones have some sort of overdischarge protection?

I'm not aware either way of anything stating that you should or should not completely discharge an iPhone to fix anything with the battery or battery meter. I can tell you that LiPo batteries have only a certain number of charge cycles in them. The good news is that if you charge a LiPo battery from 90% to 100%, you've taken off 10% of one charge cycle of life from it, not an entire charge cycle. Also, I've always been told to keep LiPo rechargeables topped up for best life. The iPhone definitely has overdischarge protection.

Thanks jzmtl and Alan_ for your replies.
I was able to confirm that my Nokias can still call 911. They are going in the glovebox of each car with a charger and an information card. (And one is going into my parents' car, whether they like it or not. Their offspring can be stubborn too.)
From the website of the official Canadian telecommunications regulator (CRTC): "What if I have a cellphone but do not subscribe to any service?
Even if you do not have any pre-paid minutes or a service plan, you will still be able to dial 911 in an emergency situation. However, you will receive wireless 911 services as they exist today. Emergency responders will not be able to use the enhanced features to determine your location with a greater degree of accuracy."

Did you update it often through iTunes?
Yes. But that didn't help anything. It was not a battery problem. Among many issues, the biggest problem was lack of connectivity to the carrier (AT&T). 95% of the time the phone would not work as a cellphone, it's most basic operation. No 3G connectivity either. Local operations would still work fine. It was not a problem with the carrier either - other AT&T iPhones sitting right next to it were working just fine. I am not knocking iPhones. They are good phones. I am knocking Apples refusal to help at all and saying to just buy a new iPhone. The latest phone to have problems was 14 months old. They would not even look at it at our cost. Buyer beware on Apple customer service.

There are reports that the new iPhone with Siri is really chewing up network resources. Apparently DOUBLING the data transferred, this has put a strain on a lot of service providers. If your have dropped calls or reduced service, this might be one of the reasons why. http://www.zdnet.com/blog/london/apples-siri-8216doubles-iphone-4s-data-usage/2194 My local provider (SaskTel) has been under fire for not being able to keep up with the demands of smartphone usage and gave several managers the boot as a result.

Bum phone, clearly. Either that or it needs a new MiniSIM Card, which AT&T would charge you around $30 to do. AT&T was great. They put in two new sim cards and a battery for free, even though the phone was bought at the Apple store and not an AT&T store. I don't know why they tried the new battery, but they did, and I appreciate their attempt. After that AT&T finally said, it wasn't them, it's the phone itself. Which I 100% agree with. But at least AT&T tried. Apple refused to even look. Did you try calling Apple directly? No, that thought never occurred to us. Our Apple store is a huge one, in a large mall in the Denver metro area. This is where they direct you to go for problems. You make appointments with their technical gurus, or whatever the name is they give themselves. I think they use the term "guru".
