Capture a screenshot in an iPad

There are times when you may want to capture what is currently being shown on your iPad’s screen. That’s easy to do on an iPad.

Simply press the Home button and then the Sleep/Wake button simultaneously. When you hear a click, the screenshot has been taken.

Use Your Android Phone Like a USB Key

If you own an Android phone, you can use it as a substitute for an external drive or a USB key. You can load files into your phone simply by plugging it in to a PC with a USB cable, then tapping on “Mount” when you are prompted by the system.

This mounts the internal storage of the device as an external drive relative to the PC, and you can easily drag and drop files or create folders on the device as you see fit.

Unsend Emails Sent Using Gmail

Have you ever sent an email and then immediately regretted sending it? If you are using Gmail as your mail client, you can do just that with an interesting but buried option in Gmail settings.

To enable this feature, go to Mail Settings in Gmail (upper right corner, under the gear icon). Navigate to the “Labs” tab.
