So, I finished writing my first iPhone App, and I have sent it out to a group of beta testers. Everybody is happy, except for this one guy who noticed that after having run my app, another app is not starting up anymore.

Almost everywhere in the iPhone, you can type text and the OS will recognize portion of the text to be hyperlinks (phone numbers, email addresses for example).
