This review is from: Griffin AirCurve Acoustic Amplifier for iPhone -Clear (Wireless Phone Accessory)
This product does exactly what it claims to do, acoustically amplifies the output of your iPhone's tiny, tinny external speaker on the bottom of the device, and it does it amazingly well! I bought it to use so I could listen to music while in the shower and I didn't want to buy an expensive powered dock with speakers just for that use and this was the perfect solution. I'm not fussy about the sound quality so much in that environment, but this thing does a pretty amazing job of boosting the volume and sound quality with no power what so ever. It appears that there is a channel for the microphone also, but I haven't had a chance to test if you can use it effectively in speaker phone mode while in the dock.

You can buy or use your original USB connector cord to charge or sync your iPhone while it's in this dock and I don't recommend you buy one of the extended length connectors like another reviewer suggests, it is designed and fits just fine with the low profile connector like apple supplies.

One caveat though: the little cradle inserts for both the first gen and 3G iPhones are made to hold phones without any external covers or cases so you can do a couple of things. One is to not use the little inserts at all but then the phone and connector are a bit floppy and don't seem well supported. Probably not the best situation for your expensive device and amplification is reduced drastically. The most obvious is to take your phone out of its cover every time you use this dock, but if you're like me you find that a small hassle and would rather not have to fiddle with it. However, if your cover is very slim like mine is (Apple iPhone 3G 3Gs Rubberized Hard Plastic Slim Case Cover - Black or similar), you can modify one of the holder inserts to work just fine. Here's how I modded the insert for my first gen phone.

I took the cradle insert for the 3G models and carefully trimmed about ¼ of an inch off each end, just enough to eliminate the tapering curve for the 3G. I then carefully trimmed the very small, hair-line ridge from where the front of the phone would fit. The 3G is slightly deeper and wider than the 1G and with these minor alterations your phone will fit very snugly in the dock and is well supported even with the case on. This is important because the speaker needs to be sealed against the cradle insert for the device to achieve the maximum acoustic amplification and for the little back support tab to provide the best support. I suppose you could do a similar operation on the 1G cradle for 3G phone.

This is a good value for the money and I don't think you'll regret it.
