So I bought this accessorie from, the site says it works with the 3gs but when I get it all set up it works as far as playing the music and all that fun stuff, my problem is the charging I connect the little pin cord to the bottom of the phone and it charges but stops my phone from playing music and playing sounds. I do see the error that it's not compatible with this device error but it still charges, very weird. Has anyone else had this problem with this accessorie? In the mean time I just connect the USB cord to the all in one and it charges while playing music that way. Any help would be appreciated.
