So, your on the lock screen but you don't know the password, crap
Open the settings panel and go into the calculator
Now, hold the lock button so it asks you to shut down, click cancel and IMMEDIATELY double tap the home button
You'll be presented with the running apps, none of them will open except one...
Find the camera app and enter it
Click the photos button
As you can see, we can now flip through all the photos without unlocking the device
And every function you can do with photos (social media, texting, editing, etc.) can also now be done. This allows you to also access every contact and text them.
So thats how it's done! This will probably only work with 7.0 since Apple is very aware of this bug. But updates don't come out very often so this should work for a while.
If you have any comments, questions, or suggestions, post a comment or send me a message and I'll see what I can do.
