      This is a jailbreak tutorial, not an unlock guide. What’s your unit, firmware and baseband?

    Randyle Vu9 years, 8 months ago

    wrong information. This is not untethered jailbreak on iOS 5.1. This IS TETHERED JAILBREAK for iOS 5.1. BEWARE before updating.

    untethered on ios 5.1 ????? ios 5.1 works with corona ??

    Alexander Nicko9 years, 8 months ago

    there is a confilct due dependencies requirement when i tried to install corona. Corona is for iOS 5.0 and iOS 5.0.1 only, so it is not possible to install corona for iOS 5.1. This is the first time that article in Jaxov is wrong, have u tried this before?
    i tried on iphone 3GS.

    Something buggy with this version.  I have used the other versions without incident but this version gives a error message “Memory Exhausted” and fails to make a custom ISPW.  I’ve googled the problem, found that others are having the same trouble but no workaround or update.
