You guys want something half baked or something stable and tested? Like tohff7 said, Corona (the exploit for userland untethered JB) only works for A5 using developers account, which is not relevant to normal users and might get them in trouble with Apple. Untethered JB works on A4 because of Limerain exploit which enable tethered JB that provide them with the opportunity to use Corona. Without an exploit to inject Corona using root access or bypassing sandbox, all we can do is wait for the JB Team to crack their head in finding the exploit. Unless they can find a hardware exploit like limerain.
