Also, a 3GS at least has HW acceleration for AES, SHA-1, and some sort of RSA bignum acceleration. Not sure what the new HW has but I suspect backwards compatibility may be a reason for holding SHA-1++ back on iOS.

They recently added support for SHA-256 (both full digest and truncated to 160 bits) hashes in their codesign system. I haven't seen it on iOS yet and suspect that it is only for OS X at the moment.
