Thanks tptacek, I'm really glad to hear that! (The first part, not the second!) That's really enough? I find it hard to believe, as that is not at all what I see in job ads, and everyone I follow and read and learn from seems to know so much. I was even going to hold off trying Jailbreak until I'd done more learning and practising. But will take heart from what you said and see what I can find. Thanks again (and for Microcorruption) - looking forward to Jailbreak!
