Redsn0w 0.9.6rc14 already on it’s way
*UPDATE* Redsn0w 0.9.6rc14 is out now
Soon after the announcement that @i0n1cs untether had been added to redsn0w 0.9.6rc13, we have received word from many users, and now confirmation from @musclenerd that rc13 is NOT working on iPhone4. I have also heard reports that the issue exists on the iPT 4G as well. For now, if you have either of those devices, stay away from rc13. A new patch should be released soon to address the issue although there is no timeframe.
