Upgrade: 4.3.3 to 5.0.1

[yubb]

Hello,

I am trying to upgrade from 4.3.3 to 5.0.1 without upgrading the baseband. Also, I've heard they stopped signing 5.0.1.
Is there a tutorial to bypass the signing, and to upgrade to 5.0.1 without upgrading the baseband?

Thanks in advance!!

That is entirely dependent on what device you have. If you have iPhone 4S or iPad 2 you are currently stuck with the firmware you have or upgrading to vanilla 5.1, although @notcom and @ihatesn0w are working on a tool to allow for downgrading newer (A5) devices. Anything older you will likely need to do some work, but I believe it can be done. Look up something called stitching. You'll need to have already saved your SHSH blobs a AND the corresponding APTicket. Most people do not have this information available, and if you don't already have it, it's probably too late.
