FaceTime is one of the major new iPhone 4 features that set the smartphone apart from others, but we’ve been hearing that quite a few people are unable to place a FaceTime call from their iPhone 4, despite both parties being connected to Wi-Fi, which is the only requirement. In fact, we had the same issue when we tried to fire up our first FaceTime chat while at the Apple Store during iPhone 4 launch. I immediately walked over the to Genius Bar, figuring that my iPhone 4 wasn’t recognizing the fact that it had a front-camera or something, and the Genius was stumped, too. He was also in charge of handing out iPhone 4 units, so we didn’t have his full attention anyway. While he was doing his thing, we looked through the Settings area to see if there might be something there. As it turns out, there was.
For whatever reason, not all iPhone 4s are shipping with FaceTime enabled. The person I was with had just bought his iPhone 4, same as I did, and his had FaceTime enabled by default, while mine was disabled by default—both straight out of the box. If you are experiencing the same, first thing you should do is go into Settings, then Phone. Right beneath your phone number will be the FaceTime toggle. Switch it to “ON” and you are good to go.
We’ve been using our iPhone for answering many an email while on the go, and one question we hear from other iPhone owners deals with how we changed the “Sent from my iPhone” text from the email signature. We figured a quick how to was in order. It’s quite simple, really, but if you tend to stay away from the Settings menu, then you would never see it. From the iPhone home screen, hit Settings, and then scroll down and tap Mail. You will see a Signature area that you can tap. Once you do this, you are editing your iPhone signature. You can get rid of the default altogether and roll with no signature at all if you like, or you can edit it to your specific preference.
Whatever you end up putting there will be used in both new emails as well as any responses you send. Let us know what you end up putting in your iPhone signature in the comments.
