I upgraded my Ipad2 to IOS 5.1 and also Garageband to the latest version. From then my Apogee Jam is stuck on blue light. It also doesn't work with other apps (Ampkit ....). I am sure it's a software issue, because its working well with my IPHONE 4!
I chose this device over others because it was supposed to work with Garage Band. I have the iPad with IOS 4.3.4 and it does not work.
Hopefully, I can successfully upgrade to IOS 5. No better experience then trying to get PC accessories to work sometimes. I thought Apples' strength was that their products just worked together.
