Since the iPhone’s recent software update, several new undocumented features have been uncovered. Walt Mossboerg has an article highlighting some of them.

The favorites list in the “Phone” module now accepts 50 entries instead of 20, there’s a new e-mail setting that allows you to BCC yourself on every message you send, and apparently the iPhone now works better with iPod car adapters.

Some readers also commented that there’s now an option for longer passcode lock periods, more robust support for IMAP mail accounts, and a host of other enhancements.
