I'm in the same situation (ipad 2 6.1.3 and mobile pod 1.5.0). worked 1-2 weeks ago - fired it up two nights ago and it hasn't worked in the past two days. Signal doesn't seem to be getting through the interface in either direction (i'm feeding the output into an amp). Hate to think it is a mechanical failure (had it for 1 mth - hasn't left the house & has only been handled 5-6 times).
If it has to be returned so be it, I'm hoping there is a fix - if anyone's got one please advise.
