Apple's iPhone is considered one of the top mobile devices on the market, and with good reason. It offers endless functionality to keep you productive as well as entertained. Since the iPhone is so chock full of bells and whistles, it's often a question of what is really needed versus what is simply desirable. One such feature is the passcode lock.
Ease of Use
With the passcode lock enabled, in order to use the device, you're required to input a four-number code to unlock it. While you can set the passcode lock to engage itself after a specified amount of time, it still creates an extra step when going to use the iPhone, which is, to some, a hassle.
Mere months ago, iPhone users rendered the passcode lock as a joke, a safety feature that was easily bypassed by even the most novice of hackers. While Apple has since updated the feature to create a more difficult-to-hack security level, it's still one that more nimble hackers can negotiate. According to Jonathan Zdziarski, author of "iPhone Forensics and iPhone SDK Application Development," if law enforcement is equipped to access locked (and therefore supposedly secure) iPhones in cases of emergency, then you can bet that cyber criminals are equally---if not more---equipped to do the same. In this case, then, perhaps the best option is to not store your most personal data on the device.
You have 10 chances to enter your passcode correctly. After the first six tries, you then go on a graduated time lapse before you can enter another guess. First, one minute, then five, then 15 and then 60 minutes. If after that point you're unable to produce the right code, all media and data information will be erased.
