all rite guys,
i was able to downgrade my iphone,
thank you very much for all ur help.

dhilzard,

i saved 5.0.1 by cydia(save my life), and updated my iphone to get unlocked because i was one of the luckiest one to get unlocked by att. At the moment, i m on 5.1, and i have saved shsh for 4.2.1, 4.3, etc, but i never used tiny umbrella to save the blobs for ios 5.0.1, will i be able to get the apt tickets or anything that will make my phone downgrade to ios 5.0.1. ? thanks

anybody? pls

how do i get the apt ticket from cydia server? i never used Tiny umbrella to save the shsh but cydia saved it for me .
THANKS

thanks for u quick reply, i havent unlock my iphone yet, i just got approved and only one step away from unlocking it which is restorting the iphone. I m jailbreaken and i want to be jailbroken untethered , what should i do in this situation? should i just restore it to fresh ispw from itunes or download the the 5.0.1 and try restore and see if my iphone4 get unlocked(using the old firmware which is 5.0.1)

downgrading my phone wont hurt the unlock because baseband cannot be downgreaded. u guys know what i mtalking about. :)

I have a shsh blob saved for 5.0,1 on my phone, and I got the email from ATT that my phone can be unlocked by imei. i was just wondering if its ok after unlock the phone, i restore it back to 5.01 and jailbreak my iphone 4? or just wait for new jailbreak to come out for 5.1?

thanks guys,

google it (key words) the iphone wiki .. u can download all the firmwares for all the idevices if u get on the right page..

delete the back ups,
itunes- edit - preference- devices- and then select the backups and delete.
