From you phone running 4.0, use Safari and type http://www.jailbreakme.com into the web address bar and following instruction. That’s it easy as pie!

So I just bought an iPhone3GS on Ebay, only to find out after the auction that the seller had upgraded to iOS 4. I’m not 100% sure which boot-rom is in the phone yet. I should get the phone this week. I know for sure that I will not have access to the SHSH blobs for the old OS.

Am I boned until a method becomes available to jailbreak an un-jail-broken 3GS with iOS4, or is there a way I don’t know about?

Any help would be greatly appreciated.

Wait for the next Spirit update (Hopefully soon)

quickce July 9, 2010, 9:32 am

I have an update.
I got the 3GS in the mail today. It is loaded with iOS4, baseband 05.13.04 and bootloader 06.04. Are there any tools available to jailbreak this now? Or is this still a work in progress?

Thanks!

If you are running 4.0 or 4.0.1 just use Safari. Type http://www.jailbreakme.com into the web address bar and follow instructions, if it won’t run its because you have 4.0.2 and then you will need to downgrade to 4.0, which the shsh may still available. For that try tiny umbrella to locate your 4.0 shsh. Let me know if you need help. I just recently did all this and those youtube help videos leave out 4 very import things you must do to accomplishthe downgrade.

I have iphone 3gs 3.1.3 which is jailbroken with spirit. I want to install OS4 in it.I have some questions:
1.If i restore my OS to 4 then will my baseband be updated?
2.Can i again jailbreak my iphone as i have previously jailbroken with sprit?
3.Can i unlock it?

iPhoneHeat July 9, 2010, 9:08 am

1. Yes
2. NO, you must be @ 3.1.2/3.1.3 (depending on bootrom) and restore custom firmware
3. UltraSn0w can unlock all baseband to date. but you must be jailbroken

ashwinkandel July 9, 2010, 3:40 pm

if i restore to OS 4 then my iphone will be like a brand new iphone isn’t it? then why can’t i jailbreak it using redsnow or other softwares.
