Known as Enhanced Push-to-Talk (Enhanced PTT), the new app brings two-radio features to the iPhone 5 and 4S.

The app supports up to 250 people, gearing it for certain types of workplaces and first responders, … Read more

Starting with the Nokia Lumia 920 and Nokia Lumia 820, the industry got a … Read more

The new Gmail features a tabbed interface that sorts e-mail into Primary, Social, Promotions, Updates, and Forums. While this does make your in-box look a bit tidier, it can make the transition to the new style frustrating when it comes e-mail alerts.

Thankfully, you can set alerts for each category, and even disable them for others. When you get an alert on your Android device, you'll know what kind of e-mail you're receiving, and whether you need to read it right now.

Before you set the individual alerts, you need to make sure that notifications for your Gmail … Read more
