I have iOS 7, and I do not like it.It's slow and clunky on the iPhone 4, and Apple doesn't seem to care.
I want to install an older iOS--preferably iOS 6--via jail breaking my iPhone 4.
If I do this, will I lose my data (not Internet surfing data but files and such)? If I will, can I retrieve my data from a backup from iTunes or iCloud, despite not being at the current iOS?
