Hi
I've just been playing around with Garageband on my Ipad2 and everything seems to work beautiful together
Remember to export the audio files as AIFF and be sure to remember the tempo you set in BIAB.
You can work with up to 8 tracks in GB for Ipad.

Then follow this guide (add the audio files you want to import to the GarageBand File Sharing area in iTunes):
