My phone says it I disabled and I should connect to itunes. I have no idea what to do and all the answers here require a computer.. Can you help?
If it is not a temporary disable ( due to incorrect passcode attempts), and is permanent, there's nothing you can do except restoring it from a backup or resetting it.
This help article clearly says that iTunes is required (either on a Mac or on a PC) to do so whether it is a friend's or apple store's.
The current data cannot be backed up but if you have a cloud backup, it can be used to restore it.
