i've got a handset iPhone 3GS, which has firmware 05.11.07 and is running pre-4 OS with the help of blackra1n

can this phone be upgraded to OS4? and if so how?
my other 3GS has an older firmware and PwnageTool does the job, but it seems that should not work on 05.11.07

iOS4 will not install with the firmware being lower than the required version, but what may I ask do you need to keep the firmware downgraded for? With the new DCMA laws you are perfectly within your right to jailbreak your iphone. Just upgrade your 3gs to 4.1 using iTunes. Then navigate to the below address in safari and slide to unlock, its really that simple.

Hope it helps, but feel free to clarify if this doesn't solve your problem.

thanks, but not sure I understand your comment about the required version - my second 3gs handset is with firmware 04.26.08 and I am running OS4 fine. my wife's however is still OS3 with 05.11.07 firmware

As for the site suggested site: it cautions not to update past 4.0.1, which I can live with, but I also need carrier unlock... any idea whether the likes of ultrasn0w would work on firmware 05.11.07 and/or how can I go about unlocking?

Do you know what baseband your phone is running? Depending on the baseband you can can try RedSn0w.

iPhone Baseband version is under the Modem Firmware Label - so the firmware I was referring to above is the baseband number you seek 05.11.07, but the article you are refering to is for older OS/firmware releases Apple firmware 3.0 and 3.1.2 so it is of no use

I am only interested in advice if you have already done this on 3GS handsets with baseband 05.11.07 and OS/firmware anything that starts with 4
