So I answered my previous post by trying my acoustic electric out with iShred LIVE and got it to work....but only once. I have the iphone 4 and am having the problem that several others have had - it says no audio input detected most of the time, and the other times voice control comes on along with my music from my ipod beginning to play.  When I plug the headphones directly into the headphone jack all is fine.  I have tried some of the suggestions already posted - got can air to blow out the headphone jack (no lint), and pulled the jack out a little bit (cause I read on one of the topics that the jack is a little bit too long).  The only way I got it to work was to pull it out a bit, and it took a LOT of jiggling to get it just right. 

Once I got it working, it was the coolest thing ever and I loved it, but to go to that much trouble every single time to get it to work seems a little extreme.  Any help or permanent fixes?  I have an ipad2 on the way and from reading everything it seems like it's not a problem on the ipad, only the iphone.

BTW I have the Griffin guitarconnect cable which I just bought on Amazon, and really don't feel like going through the hassle of having to talk to them, but I will if I have to.  I would just hope that if I get another cable, that it would work.
