Princeton University's Office of Information Technology is now suggesting that the iPad's DHCP lease renewal problem may be related to the iPad's screen being locked, either manually or automatically. The best workaround seems to be to disable automatic screen locking and avoid locking the screen manually; the downside to this is of course reduced battery life. Other (but worse) possibilities include turning off Wi-Fi or the entire iPad at the end of each session.follow link
Fun Way to Send Attachments in Mail
If you're working in a file that you want to attach to a message in Apple Mail, you can transfer the file to Mail easily: From the title bar of the file's window, drag the little proxy icon to Mail's icon on the Dock. Your Mac will make Mail the active application and open a new outgoing message, with the file attached.
(If your icon won't drag, the file probably isn't saved.)
