MY SONY ERICSSON K310I PHONE IS LOCK - Sony Ericsson K310i Cellular Phone

According to me LEO Privacy is the best and most trusted and download safeguard app to protect over 100 million users from private information leakage, with strong applock to lock up apps, convenient privacy scan to locate loophole, safe box to Hide private photo & video, Wi-Fi security to secure network safety, etc.When you don't want people to see your private things or unlock your apps, if they try to enter, the app will take a pic of the intruder, so you will find out who snooped your phone.
