A few additional notes from my post last week on the iPhone 2.0 OS. Thanks to those who passed these on via email.

• The .com button, when held, now offers three other TLDs: .net, .org and .edu.
• If you’re composing a message in Mail and press the home button to look something up, the save draft dialog doesn’t interrupt you any more. Instead, when you return to Mail, your message is still open for editing.
• You can now turn Wi-Fi on while in Airplane Mode.
• Password fields on iPhone only show the last letter typed for a short while, and then convert it to a dot. So my previous example of ••••w would only appear that way for a second or two, until being changed to •••••.
