icic.. i wasn't aware of such method before.
any info u can share here, so i can update myself also

I have a question here, currently my iPhone 4 is running on iOS 5.0.1 with untethered jailbreak, how can i clear all the content on my phone without restoring my iphone? as i know if i perform a restore it will be restored to the latest iOS, which is ios 6, so guys any way for me to clear to content?

dah.. tapi susah skit nak masuk dfu mode. kene gune care ni:

pastu aku tak tau da nak buat apa.

EDITED: finally ok da, rupenye stuck kat bootloader, fix recovery redsnow, then ok. fuhhh... clean restore, but seriously i can't remember steps that i do, adoi, never again gatal tangan restore. 4 hours trying to figure out. 

actually kan bro, aku gune care ko ajar tu, ko kate gune redsnow je utk restore, aku download redsnow paling latest kan, then tekan extra restore, then suddenly kat bootloader PUFFF ERROR! aku macam haihh.. cuak gila, then macam2 aku try nak btulkan, error 3194, 1600, -1, dia jd recovery loop, then aku tuka host smua, pastu aku g TU then aku check yg retrieve from cydia tu, then aku buat fix recovery guna redsnow yg lama baru bole, redsnow baru aku guna dia xjadi, aku kene gune yg version 9.11b baru bole.. then pas recovery fix restore gune itunes then settle, aku da sedih gila time tu takut rosak. now finally phone da fully restored to original 5.1.1

Btw aku ada satu soalan penting, kate la smalam kan, kan phone aku da jailbreak, then aku nk restore xbole, kate la aku give up then aku jadikan DFU mode, pastu aku g itunes tekan restore, apa jadi eh? means if i update my jailbreak phone through itunes? phone jadi brick ke?
thanks bro! I am really relieved bro.
