How can I tell reliably if my Android App is running on a device with JIT?

Question

Is there a way to test, from within an android app, if the device it's running on is actually using the Froyo JIT?

I ask because I know that 2.2 has a JIT, but we've already had a few test builds that seem to lack the JIT. So it's not a case where you can just test for the api version and be assured you've got the JIT.

Looks like you can use reflection to see if java.lang.Compiler exists and then to try calling some methods on it to see if they work or return nulls.
