So like the title says, my iPhone 4am is jail broken with evasion for 6.1.2 and I was just scrolling through my contacts and about to text someone when my phone suddenly tells me I have no contacts. I try to respring and my phone gets stuck on the apple logo. I finally get it back to the home page using the top volume button on start up and now I still have no contacts, all my messages and photos are gone and most of my tweaks. Cydia is still there along with a few other apps. Someone please tell me what the **** just happened and how do I fix it if I even can
