Sorry not possible as of right now. You have to preserve your baseband firmware when you update through shsh blobs and ios 5 shsh blobs are different than 4.x.x. I wouldn't do it till it's announced on redmondpie.com. They always post helpful things related to the idevices. Although I may be mistaken but I am pretty sure. Just try google searching a bit.
