go here or just read the below. if u did that ipad/redsnow jailbreak unlock and now ur stuck with recovery and itunes with work with ur iphone cause of ipad firware on it.
first of all if u jailbrked with the ipad firmware with redsnow....and took the risk in order to unlock..now ur iphone has the ipad firmware...and now ur stuck at recovery...and when u try to jailbreak again u get an error (the above picture posted by swoosh0217
here is what i did that helped me, after 2 days of searching.
first of all, (You have to restore to a 4.2.1 custom firmware made with pwnage tool)
since i am on windows operating system, i can't make the custom filmware since pwnage is a mac program.....so what i did is that i searched for one that was already made. the link is below
so 2 things we will need is, 1. the custom firmware made with pwnage, and 2. ireb
NOTE: PLEASE WHEN WE BEGIN, U WILL NEED TO PUT UR IPHONE IN DFU MODE (SCREEN SHOULD BE BLACK) AND NOT RECOVERY MODE.
In recovery mode itune won't let u restore because it will say u can't restore because of that ipad firmware.
In DFU mode: when u try to restore in itunes (with the custom firmware) u will also get an error number...ireb will fix this.
oky lets start, i just hope u understood what i wrote above.
here are the steps
first download the custom firmware 4.2.1 for 3gs made with pwnage tool in mac (thanks to the person that unloaded it

second. Download ireb

third. put ur iphone in dfu mode and open itunes and shift seletect the custom firmware u downloaded....u should get error like 1601..
if u get the error, open ireb and select iphone 3gs and let it do its thing and when its done now try to restore again with itunes (third step again) and error wont come up again.
then now rejailbreak again with redsnow.
