Convertbot [$0.99 - iTunes link] has seen their latest update, version 1.4 for iPhone (and iPod touch), rejected by at least 2 of Apple's 40+ App Store reviewers because the icon they're using for "Time" (the same icon they've been using since 1.0, mind you) is nigh-identical to Apple's built in "Recent" icon, and that was enough to raise that troublesome "user confusion" flag at iTunes HQ.

They're going to try and find a different yet equally minimalist icon, and we're going to start counting down to a letter from either Phil Schiller or the FCC...
