i have a CDMA 4.0 iphone running 4.2.8(8E401). I JB using jailbreakme.com and has been working fine.
i want to upg to JB 5.0.1 untethered but i'm not sure the steps to get to 'square 1'.
instructions say "if you haven't upgraded to 5.0.1, do it". but, i'm not sure what that means. do i just go to itunes and upgrade to 5.0.1? i'm used to the old days of JB/unlock where if you upgraded your firmware/OS you bricked your phone.
in brief, someone please tell me what i need to do to get to 5.0.1 to start the JB process from a previously JB 4.2.8 phone. if it really is just 'go to itunes and upgrade', i'd appreciate the confirmation. if i need to restore/upgrade, or some other secret handshake, please let me know.
