Oh, and just in case you wanted my opinion on the new OS for iTalk/iTap/iWhatever, don't upgrade. There is a reason they put nearly 1 gigahertz processor in the new devices. Fortunately I haven't upgraded my device simply because I spent so much time customizing it (and adding features that, ironically, are in the new OS).
if you already upgraded, don't sweat it. They'll get it patched up next year ;)
