Happy Valentine\u2019s Day to all you iPhone lovers out there. Just a word of advice: You might want to keep your beloved smartphone close for the time being, because the iPhone passcode lock feature has been hacked.\n\tThe Verge was first to report on an iOS 6.1 security hole that makes it possible to bypass the iPhone\u2019s passcode lock. Once your iPhone passcode is hacked, the perpetrator can listen to your voicemail, check out your apps, use your Starbucks card to fill up on caffeine or turn off the Find My iPhone tracking feature. In short: It lets a hacker do just about anything they want with your iPhone.\n\tAs of this writing, Apple hasn\u2019t commented on the bug, but it\u2019s no doubt only a matter of time before the company issues a software fix. In the meantime, there are several third-party apps that can help add another security layer to protect information on your iPhone. Here are three examples:\n\t* Dot Lock Secure (David Lane), $1, lets you use a "dot lock" pattern (similar to some Android phones) instead of the iPhone\u2019s passcode lock to secure your device. The app can also take photos of iPhone thieves and provide other security features. The current version was released July 10, 2012, and has a 2.5-star user rating in the App Store.\n\t* Mobile Vault (Cy Web Solutions) $3, promises AES 256 cryptography security to protect information added to the app\u2019s pre-defined templates for credit card numbers, email accounts, website logins and bank accounts. You can also create unlimited secure folders to organize personal items, including photos. The app has a five-star rating based on six reviews, but it hasn\u2019t been updated since October 31, 2011.\n\t* ContactsPro (Demodit GmbH) $2, lets you hide selected contacts in passcode-protected areas, which you can import into the app from your iPhone\u2019s address book. The app (last updated in December 2012) only received an average rating of 2.5 stars, however. And one example of the kind of secure information you can protect, listed in the app\u2019s iTunes product description, is offensive to say the least. \u00a0\n\tDo you use a third-party app to protect sensitive data on your iPhone?
