Hi all. I currently have a ps3 slim running 3.55 cfw and have seen things on other sites regarding DEX units. I know they are dev units and there is now a way to convert your CEX (consumer) unit to DEX. The DEX version of 4.21 fw has even been leaked. My question is, what if any, is the advantage to switching to DEX, as far as being able to play backups. I know it can play all current games from disk and i know deank has even released a version of multiman for dex units but do they require special eboots? are they hard to come by? can i just use multiman and rip them and play like i currently do? so many questions. also what is the easiest and safest way to switch. can i later go back to 3.55 or even cex. i know i asked alot of questions but i hope i can get some answers. thanks.
