No, because it's a trademark you always use the intended capitalization. It looks weird, so I imagine that style guides would suggest getting around this by using phrasing such as: "The iPod", "Those iMacs", "With iMovie", "Apple's iLife Suite", "On the other hand, iDVD", "Lastly, iWork"...and so on. There's always a way to rewrite the sentence so that the "i" doesn't end up in front.
