Still stuck with an Epic 4G Touch (or stuck a relative with your old one)? If you've been holding off on flashing some of the previously leaked Jelly Bean builds for fear of stability or finality, Sextape has released what is rumored to be the final build that will go out as an over the air update some time in the near future.
Build FK23 can be downloaded here, and is relatively easy to flash. Here are the instructions
1. Download stock TAR.MD5 file (link)
2. Download Odin (see thread)
3. Download appropriate drivers (see thread)
