The algorithm was bunk. Even though it said it used a 64-bit key, the key could be brute forced in the amount of time it takes to crack a 30-bit key. This is good reason not to trust proprietary encryption.

I just read a book which discussed the A5 algorithm. It was written by Bruce Schneider, Secrets and Lies
