Agreed. I'd also note that ECB, CBC, etc, have basically nothing to do with the _algorithm_ being used (in this case, AES). The idea of an IV, ECB, CBC, etc are just techniques to be used to make the results of block ciphers more secure, regardless of what algorithm they use. That's my bigger problem with the "AES is broken on iOS" claim based on IVs. The two things are only loosely related.
