I love my iPhone as well, though at times I am less than thrilled with signal strength. I use the eye-chart. The EZ Level app can be used as a goniometer for range of motion documentation. It would be nice if all the apps would send incoming calls to voice mail when in use.
I think the iphone feature which has most revolutionized my business is simply the visual voicemail. I'll never go back to regular voice mail again ("you have thirty messages...message #1..."--uggh!).
