[mmm286]

Hi,

I'm a newby in jailbreaking. I have an iphone 3g.

Could I downgrade to 4.1 without having 4.1 shsh certificates saved?

Many thanks and sorry for my english!

Thanks.
I'm lost. I've saw some web pages where they say that the ipone 3g can downgrade without shsh certificates

Could you help me please?

You absolutely have to have SHSH's save for the version of the iOS that you want to downgrade to.

Well.
I only would like to say that is possible downgrade the iphone 3g without shsh blobs. If you have a 3g and you would like downgrade 3g ios 4 to 3.xxx you can do it without shsh.

Thanks!
