Not sure if this has already been mentioned, but on my iPhone 4 I often see thread links in larger text - is this a quirk of the iPhone or intentional?
Oh, and if you have an iPhone and you're wondering how to grab screenshots - press the on/off + action buttons at the same time and it'll drop the screenshot into your camera roll.
Hope it works for you, if not please don't shoot the messenger( but since this is holiday season maybe the phrase "Blame the bearer of bad tidings" would have fit better?..) Either way best regards to yah
