Placing a call on hold on the iPhone 4
By now, you know that the Hold button from previous generations of iPhones has been replaced by a shinier, newer FaceTime button. Steve Jobs attempted to downplay this major interface change by pointing out that the Mute button was just as good as its old pal Hold, but that button only serves to mute you and not the person you're on the line with. The Hold button would ensure that the person on the other line could hang out for a minute, even if he had to do so in silence.
Fortunately, there's a way around this. Press and hold the Mute button for 2-3 seconds and this will activate Hold. Tap it once to deactivate Hold and turn it back into a Mute button.
Connecting the iPad Camera Connection Kit and USB thumb drives
If you have a USB thumb drive and you want use it with the iPad Camera Connection Kit's USB dongle to import photos onto your iPad, then this tip is for you. All you have to do is take the thumb drive and create a folder on it named DCIM. Next, copy the photos and video you want to import into the Photos app on your iPad into that particular folder. Finally, plug the USB thumb drive into the dongle. The iPad will recognize the thumb drive as if it were a camera and import the photos and videos.
Connecting the iPad Camera Connecton Kit and your iPhone
If you have an iPhone, with the standard Apple Sync/docking cable and the iPad Camera Connection Kit's USB dongle, you can import media created on your iPhone onto your iPad by simply connecting them together. The dongle treats your iPhone just like it would any digital camera. We tested it with the iPhone 4 and successfully transferred photos and video we made with the phone onto the iPad. If you've created an iMovie, you can use this tip to see that iMovie on the iPad's larger screen!
iPad & iPhone: Restrict 3G Data for Limited Data Plans
Are you one of the unlucky people that ended up buying an iPad Wi-Fi + 3G or new iPhone 4 only to find out that AT&T no longer offers the unlimited data plan for either of these devices to new customers? If that applies to you, then you should consider this tip. It will help you to reserve your 3G data for only when you really need it, and it will definitely make everything route over to Wi-Fi if it is available.
This old tip is usually offered to iPhone users to conserve battery life, but now it has new life on the iPad and for new AT&T iPhone customers that can no longer get the unlimited plan.
Launch the Setttings App on either iDevice. Go to Settings > General > Network on the iPhone, or Settings > Cellular Data on the iPad. Locate the following, Cellular Data and Data Roaming, and make sure that both of them are turned off. The latter one is usually off by default.
All data traffic on the iPhone or iPad will now be diverted to the Wi-Fi connecton regardless of circumstances and you'll be able to use your data plan in a miserly fashion.
If you are on an iPad, there is one side effect: you will no longer be prompted to create a Cellular Data Account if you don't have one already. That prompt may appear periodically until you either do the above or activate a Cellular Data Account. In any case, this idea is the cheapest way to get rid of that prompt.
Need to access your 3G data again? Simply switch Cellular Data back on.
