Please do take note that we are not going to discuss what’s new in iOS4 (operating system) as it has been pretty much covered elsewhere. This article is basically- what you can expect with the new iPhone 4.
1. Update all your applicationsFirst things first, check for application updates. If you have lot of applications installed in your previous iPhone 3G or 3GS, chances are they will need to be updated again so that they can take advantages of the new iOS4 features and iPhone 4 capabilities. So before you start trying out your existing applications on iPhone 4, take a moment to check if they need to be updated.
2. Where’s Facetime?This is probably one of the first thing you’d like to explore on new iPhone 4, but where’s the Facetime app? Facetime is actually not an application, in fact, it’s an option available (for now) only when you make a call via WiFi to another iPhone 4 user.
Facetime is turn off by default. To turn it on, go to Settings → Phone and turn Facetime on. Carrier activation might be required. Learn more about Facetime.
3. You’ll need a new wallpaperWith retina display, everything on iPhone 4 looks amazingly vibrant and high quality. The screen supports up to 960×640 pixels at 326ppi, approximately 4 times higher than the resolution in a iPhone 3Gs. In another words, it makes your current wallpaper looks weak and you’ll need to look for a higher resolution wallpapers :-)
4. Try iMovie for iPhone 4iMovie for iPhone4 is a light version of iMovie for Mac and it’s awesome. It allows you to edit and share your recorded videos on the fly. And did we mention all videos recording with iPhone 4 are in high definition (HD)?
iMovie for iPhone 4 cost $4.99.
5. Tap to Focus Object – VideoEven the smartest gadget can use a some human touch. While video recording, you can tap on different objects on the screen to have iPhone focus on them.
6. View widescreen while RecordingIf you swap from camera mode to video mode, you’ll notice that the objects are actually getting closer. That is because video recording is done in wide screen mode. To display in wide screen while recording – double tab the screen.
7. Search Web, Wikipedia on the flyBy swiping right on the home screen, you’ll activate Spotlight. Type in something and scroll all the way to the bottom and you’ll noticed two additional search options have been added, respectively the "Search web" and "Search wikipedia". Both search uses Safari browser.
8. Mirror, Self-ShotiPhone 4 comes with an additional front camera. By clicking on the camera icon on the top right, the front camera is activated instead of the back. We thought this could be useful for those who want to use their iPhone as a mirror, or perhaps, it makes taking self-shots easier too!
9. The iPhone 4 reception problemThis is the question most people are most concerned about. To be fair, yes signal bars do dropped when gripped – they call it the Death Grip.
However, signal drop only happens in areas where receptions are weak, so it very much depends a lot on your service provider. The problem is mild, don’t get too worried about it.
