At the "Hackers On Planet Earth" (HOPE) Conference in New York this week, forensic scientist and security expert Jonathan Zdziarski identified several holes and back doors currently on the iPhone. There's even a packet sniffer that's running all the time. Apple has yet to respond to it. It's important to understand that whenever you're using a connected device, whether intentionally or unintentionally, it could reveal information to interested parties. In his presentation, Zdziarski revealed some of the data that is constantly leaked out by the iPhone.
Kim wants to switch carriers and wants to know the best option for getting an iPhone. Leo was going to suggest T-Mobile, but that's where Kim is and she doesn't want to have a contract. Leo says that without a contract, she'll have to pay for a phone unsubsidized. She can also buy the iPhone 5S unsubsidized and make payments on it, but that's just like having a contract. Should she wait? Leo says we'll know when the iPhone 6 is coming out in a couple months. It'll probably be out in September.
Larry needs to get a new charger for the iPad. Leo says that the iPad requires 10w of charging and most chargers are only 5w. So he'll need to pay close attention to the amperage. He could use the same 10w charger for both his iPad and phone, because the phone will only take as much juice as it needs. If it takes forever to charge, it means the charger just isn't powerful enough. He can boost the charging time by putting the iPad into Airplane mode.
Wesley has a friend who's phone is fairly new, and it drops to 30% really quickly and shuts down. Leo says that's not right. If it's still under warranty, he should take it back. That isn't the sign of a bad battery. Batteries either work or don't work. What uses the battery most is a screen. So an app really wouldn't kill it so suddenly.
Michael is trying to decide between a Samsung phone and the iPhone, and wants to know what phone will let him talk on the phone and use the internet at the same time. Leo says that's a network feature and not so much a phone feature. Currently, it's only available on AT&T and T-Mobile. But Verizon and Sprint are moving towards LTE and then he'd be able to. The chat room says that this is possible on some Android phones, if the network has turned on the capability.
Diego wants to know if he should wait to buy iPhone 6 when it comes out or make the move to the Samsung Galaxy S5. Leo says that we don't know what's going to be in iPhone 6 and the earliest we'll know is the Fall. We have a hint at what it will be able to do with the preview of iOS 8, though.
YouTuber Marquis Brownlee got his hands on a sample iPhone 6 Sapphire screen and Leo says it's looks quite legit. The screen is extremely wear resistant and you can't scratch it at all. It's also a 4.7" screen which is the largest iPhone screen Apple has produced, if legit. You can watch Marquis' video here.
Alan would like to delete all the emails at once on his iPhone. Leo says if that email is on an IMAP server, then the messages are on the server and not on his phone.
Tom's contract with Verizon is almost up and he's thinking of moving to another carrier. Leo says that Verizon is on CDMA and T-Mobile and AT&T is on GSM. But pretty soon all will be on LTE, so it won't matter anymore. He wants to move to a no contract carrier. His mother wants to get an iPhone 5S. Can he get that off contract? What about the iPhone 6? Is that coming in the fall? Leo says that's the speculation. Will it be larger? Leo says nobody really knows. There's been pictures of larger screens, but they're prototypes.
Contacts can be organized into groups on the iPhone or iPad to make them easier to find. However, it may not immediately be obvious that this is possible because Apple still doesn't allow you to create those groups on iOS 7 -- you can only view them. To create groups, you must do it in iCloud or from your computer. Here's how to create groups using both methods:
