Hi
I have iphone 3gs, on 4.1
Tried Limerain & greenpoison but didn't work.
So I tried snowbreeze. Went through it all created the custom firmware, went to itunes, left shift & restore, found the snowbreeze firmware and got a message saying could not be restored because the firmware file is not compatible.
When you say limerain and greenpoison didn't work--any details you can give? (Did you restore first, did the process complete, etc?) I'd try looking here and giving it another go step by step. There's a video guide there as well.
Hi
When I tried greenpoison, must have tried 4 or 5 times and kept getting try again after the button holding/countdowns.
Limerain got to the release power button and seemed to stick.
I had trouble with greenpois0n as well... i found when it went to the last 15sec countdown it disappeared after 10 or 9... but i had to hold it down and in my head kept on counting down and then releasing the home button.
Make sure you try and JB after a fresh Restore and after activation but before syncing...
good advice as i did jailbreak from my phone it was slugish but after reading farbod's suggestion on his faq i re did it and phone was lighting fast compared to before.
