Hey everybody, I found a way (Anyone how to root the mesmerize with gingerbread? - xda-developers) to root the stock GB 2.3.4 ROM without flashing a pre-rooted ROM via Odin. You DO have to flash CWM first, but after that, you just have to open the file in the link in CWM. I tried it last night, and so far it's worked well. It installs Superuser automatically, and root-specific apps work great. It is a pretty small file, and it only takes a minute to flash it, but don't forget to run a backup on CWM first.
