Ok this is a weird one. My wife has an iPod (last gen). She is running 6.1.2 and i just JB. This iPod used to be JB when she was on iOS 5. Now the weird part, when i add springtomize the contact app goes away, i still have access to the actual contacts ( when writing an email or just a spotlite search), but the actual app is gone. I looked in all the folders it is not there. I can remove springtomize and the contacts app is back.
