Here is a useful accessory for your iPhone 3G and iPhone 3GS, the Bandshell iPhone Case, which as well as protecting your iPhone is designed to reflect sound from the iPhone’s built in speakers.
The Bandshell iPhone case is ultra-slim, durable and improves your iPhone listening and viewing experience. This dual-purpose iPhone case amplifies the volume and sound quality of your music and videos, without the need for extra speakers or cords. The Bandshell’s flat side makes it easier to watch movies and videos without having to hold the iPhone or lean it against something.
The built in speakers on the iPhone aren’t the best if you want to watch a movie, I usually end up using some headphones or a portable speaker, so this case could end up being quite useful depending on how well it works.
If you want one, the Bandshell iPhone Case is available in a range of funky colors for $19.99 from Bandshell.
