For some reason people keep posting PS3 DEX stuff in the CEX Duplex thread... please do not do this as we don't have time to keep moving the posts to the ongoing DEX threads so we'll just delete them.
To discuss DEX topics, DEX guides, DEX fixes, DEX patches, DEX videos, etc use the (2) ongoing DEX discussion threads
Both of these DEX threads are Sticky'd in our PS3 Hacks & JailBreak
Forum in case you can't find them without the links above.
Finally, here is a PS3 CEX to DEX to CEX Tutorial By Yayes
for those interested in reading what is involved in converting their PlayStation 3 console.
