Ever since Steve Jobs raised the bar for executive keynotes, I haven't really bothered to RTFM for any of Apple's products (two exceptions being Final Cut Express and the iPhone SDK). So I've been happily amused to discover two iPhone tricks on my own.

The first, which I submitted to the TipBITS sidebar on TidBITS, is the iPhone screen capture button combo:

"Press the Home button and Power button briefly at the same time, and an image of your screen will be saved to the Photos app..."

(search for "iphone screen capture" on the TidBITS website).

Another trick is declining incoming calls when your iPhone screen is locked. As you probably know, when the screen is locked and your iPhone is ringing ("Ring, ring!"), it appears as if you can only slide to unlock, and thus answer. But pressing the Power button twice will actually decline the call!

Usually this will just send the caller to your voicemail, but if you're on a GSM network that supports standard * commands, you can use the *67* redirect option to route your incoming call to a landline.

If you're not sure how that works, feel free to leave a comment and I will clarify, or try Googling for an explanation of GSM * commands
