Do you have to FULLY charge the battery?
I will be receiving my iPhone 4S this afternoon. Do I need to fully charge it before I use it? I am so excited that I am going to want to rip the box open and start playing with it right away but I want to make sure that I am not going to screw up the battery.

Some do recommend letting the battery run all the way down then doing a full charge. Apple will say it doesn't matter.
It's up to you. I usually let it run down all the way on a new device then do a full charge but i don't worry about it afterwards.

It doesn't matter. Lithium batteries do not retain a memory. You can charge/discharge as much as you like. It is recommended that every once in a while (maybe once a month or two) that you do a full charge and discharge, but you won't hurt the battery if you do a partial charge on a regular basis.

It really doesn't matter, however, I ran mine all the way down three times when I first got mine on the 14th. It's more of a habit than anything else. I've never had an issue with any of the batteries on my iPhones, though. I can easily go more than 2 days on one charge with my iPhone 4S.

I guess you are right...I could rip open the box, charge it and play with it at the same time. My Samsung came with a note on bright green papaer that stated "Do not turn on the phone until you fully charge the battery". After follwoing the instructions, many people told me that I really did not have to do that. I was curious if the iPhone was the same.

it does not matter in lithium batteries but there's nothing wrong letting it drained to zero and then charged it. I did two battery cycles and so far I haven't encountered any problems

I know many people that say with lithium batteries there is no memory, and you can charge it as much and as often as you want. Personally I've always let my smartphone die or get to 1% before charging; many say it doesn't matter, but I have the best smartphone battery track record of anyone I know.

I believe the half of varaiable in the statement 'YMMV' (Your Mileage May Vary) is how something is used. There is a difference of over 5 mpg in my Jeep when I drive it vs my wife, and her first iPhone (3G) would die two times and be half dead by the time my phone was dying. I was really suprised to read people having issues with the iP4s, as mine lasts until I go to bed with about 3-3.5 hours of Pandora while at work, right in line with her iP4 with little to no streaming.

I used to be really careful to charge/discharge completely on my devices. But after reading about lithium batteries, I'm convinced it can't harm them to charge/discharge when you need/want. As long as do a complete charge/discharge around once per month, you should be fine.
