Upgrade 3gs ios 4.1 to 4.2.1 bb 6.15 no sh blobs. Possible?

[rossdisco]

Hey All,

I have 3gs ios4.1, ipad baseband. I would like to upgrade to 4.2.1, though if i am right in reading then i cannot do this without saved sh blobs(which i do not have). This iphone has been on ios 5 at some point, but i much preferred ios4.

Is there any way to get around the point that apple are not signing 4.2.1 as i know this is the only reason for which i was able to run 4.1 without any problems?

I could go ahead and try, but thought i would ask the experts first!

Thanks Loads!
