allthough this BLE-Shield board is for the one I created, not the RedBearLabs one, I will try to help you out
My experience with the firmate based BLE-Shield from RBL is somewhat low. I think you can get support from their webpage: http://redbearlab.com/bleshield/
Theis lib is available from: https://github.com/RedBearLab/Release/r ... v1.0.2.zip
and they have an iOS app available as well: http://itunes.apple.com/us/app/ble-arduino/id547628998
We I remember correctly they have a library for iOS as well to speed up iOS app development as well.
Finally I think you will get help from them as well, if you post questions to their support forum.
Thanks for contacting me using this forum,
