Minor correction but 4.1.0 will be a Warm Boot exploit. You can launch the exploit from the console after it's turned on essentially (Similar to 1.0). It still makes it a software only solution and very valuable though, imo. Who knows when it'll be released though. It's currently a private exploit. People sticking on 4.1 are going to get stuck on it for a long; at least until you get an emunand. So consider if waiting for a possible warmboot is worth it I suppose.
