One of our favorite iOS options is the option to group email messages that are part of a discussion (like a collection of replies to one specific email) into threads. It reduces the clutter in your inbox and we highly recommend it. You turn it on or off by launching the Settings app, tapping Mail, Contacts, Calendars and then toggling the Organize by Thread switch on or off.

We generally update our iOS apps on a regular basis via iTunes or wirelessly over the air. But, one problem with the latter method is that apps over 20 MB will only download over-the-air when you have a Wi-Fi connection. Usually, when we start these downloads, there's the inevitability we'll leave the Wi-Fi coverage area and will need to stop the app download temporarily. Here's how: locate the app that is currently downloading and you'll see a progress bar on the icon. Simply tap the icon before the download is completed and the icon will display the word "paused. " It will not start again until you tap it.
