Well, that is what HDMadness claims anyway.. until people with flashers give it a try and report back there isn't much feedback to go on although it definitely doesn't have as many features as Rebug's yet that's for certain.
It would be nice if this PS3 CFW at least gets to a point where flashers aren't a requirement though, only time will tell for sure... as far as I know the demo bug is fixed, not sure on the category bug in v1.1 but I know it's being worked on if not.
My only thought is perhaps the same reason Rebug did 4.21 because it's what they were working on all along so he stuck to 4.30. I can ask him the next time he e-mails us though sure, but if the files are the same as you say then that's a good question indeed.
Unfortunately I disagree, and since I'm the one taking the time to write the articles you are SOL. If you'd like to write, by all means have at it and we'll promote yours instead saving me countless hours each day.
