> As of today, B2G builds would be running JäegerMonkey & IonMonkey with the Type Inference enabled, in nightly versions of Gecko 22.

> IonMonkey is a big pieces of software which was new in Gecko 18. It has been disabled in b2g18 to prevent any additional risks because b2g18 stands as a second ESR. Now, that we are focused more on improving IonMonkey and that it is used daily since Firefox 18 releases, we have no reasons to hold it back.

> In a few weeks, Gecko 23 should see the landing of the Baseline Compiler as a replacement of JäegerMonkey. This will enable the JS team to reduce the memory usage caused by Type Inference in Gecko 23.

> If you experience any trouble related to the activation of IonMonkey, please create a bug filed under "Core > JavaScript Engine" as a blocker of Bug 849103.
