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: http://www.amazon.com/6279Q595-Replacement-Battery-1600mah-iphone/dp/B001UGAX82/ref=sr_1_1?ie=UTF8&s=electronics&qid=1272151476&sr=8-1-spell 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.
