After millions of Apple users rushed to download iOS7, many iPhone owners are discovering the latest operating systems leaves their devices susceptible to security breaches.

A hacker has figured out a way to bypass the lock screen on iPhones and gain access to photos, emails, tweets and other personal information.

To override a locked iPhone, the user swipes the screen to open the new control panel on the lock screen, and, after a few more clicks, they are able to access all of the apps running on the phone.

CTV reporter Brad Macleod spoke with iPhone users on Stephen Avenue Monday afternoon and demonstrated the security loophole on the phones of Calgarians.

Brad successfully gained access to all phones with the latest operating system update. Calgarians were alarmed by the ease with which the locked phones could be breached.

“You broke into my phone and I feel a little violated,” said Morgan Messenger. “They (hackers) could take my personal information really easily.”

Soha Zia is concerned of the possibility a hacker could commit identity theft with the information on her phone.

“You could steal someone’s credit card info,” said Zia. “I have all that stuff on my phone.”

Shawn Kunst says he’s always aware of where his phone is and is taking the security risk in stride.

“It’s (the security issue) a little bit of a concern for me but not a huge concern,” said Kunst. “The phone never leaves my side unless the girlfriend checking it.”

For those who are concerned with the iOS 7 upgrade, downgrading to the previous operating system may not be an option. According to Curtis Quinn, the owner of Calgary’s Phone Freaks, there is a very limited window to revert back to iOS6.

Quinn says phone owners should research upgrades before installing.

“If you think iOS7 has what you are looking for then do it,” said Quinn. “Don’t just do it ‘cause you can because that is when you are on the phone to us asking to downgrade and we can’t.”
