Confirmed working after OTA update 2.2 ED01.
I too confirm that the method at the top works on my Fascinate after OTA update 2.2 ED01. WOOTS!
Fascinate ED01 Root Linux !!!
Ubuntu Fascinate Froyo ED01 Root !!!
I added those 2 lines so that Fascinate owners who use Ubuntu or Linux will be able to find this page! There are some "throw your hand over your shoulder to wipe your butt" style methods that I found for Windows which are tricky and actually wipe your data. Unlike the procedure at the top above is what I used with my first 2.1 build on the Fascinate and it still works, and as you would expect from any rooting process, keeps your data! Again, woohooo!
