Just wanted some advice just so I can be sure.
I have iPhone 3G with 02.28.00 on baseband 5.8 with firmware 2.2 and with yellowsn0w fully working.
My question is I want to upgrade it to firmware 2.2.1 but want to keep the unlock with yellowsn0w running.
Am I right to say that if I used Pwnage tool 2.2.5 to make my custom 2.2.1 firmware image and restore it onto my iPhone will keep yell0wsnow intact? However if i used quickpwn i would then loose yellowsn0w?
Hope you can clarify.
