If you're getting the Macworld jitters, easily identified by the recurring dreams of Steve Jobs showing up for the keynote with nothing but a loaf of bread tucked under his arm: "I give you... the iLoaf! Oh, and one more thing, here's some butter." then you might be glad to hear the latest bit of rampant speculation, just to take your mind off things. Apple just busted out the iChat Update 1.0, which "renews the .Mac certificate required by iChat for encrypting text, audio, and video conferences." But that's all Apple is saying for now, instead keeping mum with a vague "This document will be updated as more information becomes available." It seems a pretty odd time for Apple to be updating iChat encryption and other vague features, given the fact that Leopard is right around the corner, so we're going to chalk this one up to Applephone interoperability, specifically of the video conferencing ilk. Mac OS X 10.4.9 is apparently just around the corner as well, and we're getting good vibes from all these software updates -- hardware releases seem just as good an excuse as any. Then again, an iLoaf wouldn't be half bad. Mmm. iToast.
