I currently own a Iphone 3GS. I went to best buy and tried out some dock units ( about 90% of them worked with the 3GS ) Some sounded ok and others sounded good, but did not get really all that loud. I mainly use it for when friends come by and what not, so i like to have my music pretty loud while also sounding good. Could anyone recomment any good speaker docks that work with the 3GS, Are loud AND sound good? thanks!
