help upgrade to 3.1??

[kylepianoman]

I have 3.0 currently installed (jailbroken)
how do I get this to 3.1 without losing my jailbreak?

do I use winpwn or do I have to wait for devteam to come out with something

Development of winpwn stopped about 18 months ago. Depends if you've got a 3g or 3gs though

Find someone who will build a custom ipsw file from a mac. If you have a 3Gs, you are out of luck for the moment. Visit Dev-Team Blog for the official news and you will find people that can send you the proper custom ipsw file in the comment section. (That is unless you have a 3Gs)
