    Default upgrading Iphone 4 4.2.1 jailbroken recently hardware unlocked to 6.1.3
    hi guys,

    i have an Iphone 4 that was using turbo sim, and was jailbroken on 4.2.1

    we recently had it factory unlocked (hardware i guess they do it) and the jailbreak is still there.

    if i download the 6.1.3 IPS Firmware from here, do i simply upgrade on the Itunes and all should work fine? or i will face erorrs?

    Br,

    Seth

    Since your iPhone is jailbroken, you need to put it under pwned DFU mode then do a restore to 6.1.3 using iTunes. Note that by upgrading to 6.1.3, you will lose jailbreak and the baseband will be upgraded to latest version. If the factory unlock (IMEI unlocking) is not working, you can't use turbo sim anymore.... Good luck
