I have a quick question for anyone willing to field it: I'm pondering ways to distribute signed pkg files to a ps3, and I'm wondering if you could use the PSN Download Manager/booster, and send the signed file over to the psn in lieu of the actual demo or game downloaded.
I assume it hashes the file for an md5 sum or something to prevent this. However if not it may be a fairly simple way to get signed homebrew on a legit system.
edit: tried it. Got an 80029564 error. Damn. As a followup, I'm reading from Kakarotoks that geohot's signing tools are incomplete and don't actually sign the pkg itself, only the self files. which would explain the failure I am experiencing trying to get the ps3 to accept an unsigned pkg. His close sourced MFW apparently patches out the PKG check.
