I need to temporarily jailbreak my iPhone 4 to fix Apple's iOS 6 bug making it impossible to access Japanese-to-English dictionary.
All I need and want to do is delete Japanese-to-Japanese dictionary.
Is it possible to tethered jailbreak iPhone 4 temporarily, delete the relevant folder, and merrily continue using the device in a non-jailbroken fashion?
/User/Library/
folder. If so, then you could backup/restore after you jailbreak and be fine. – grg♦ May 28 '13 at 13:43
