I have bought griffin itrip last year it worked fine but now it’s not working, i have always used my iphone 3g with it but now that i have an iphone 4, the itrip will not charge the phone or play the music on the radio. Whenever I am trying to play music it just comes out of the speaker of the iphone, I have looked on the internet but i can’t find the answer. If anyone can help me then please reply as soon as possible!
