Question On iPhone 3G Replacement Battery?

[Anthony82]

I'm always very cautious about ordering things off of the internet. I was wondering if some of the batteries I see on Amazon are worthy of buying? I have the iPhone 3G 16gb Model, I've had it since launch day of July 08 and It's to that point now where it only lasts me a half day, Full Charge. So I seen a bunch of them on Amazon, and some other websites. This was the one I was

Interested in getting:

I know how to take the phone apart just fine, I've done it a few times to clean out dust under the screen, so I'm not worried about that, I just want to know which battery is best, I don't want to order one and have it be all screwed up or even worse then this one.

If anyone has replaced there battery and has a good one, and some info on where and what kind you bought, the help/advice would be much appreciated.

Thanks.

Just buy that.
AFAIK all the different sized iPhone models, use the same memory. (IE 8, 16, and 32GB 3G use the same battery.)

With the old iPods, I believe they had different battery lives due to the use of one, and two platter HDDs in there. The two platter made them thicker, so there's more room for a better shaped battery.
