the cons of 4.21 are:
a. no codeunique
b. 3.55 psn games fix are not working (you should make a new fix, use darkeboot fixer 5.0, patch them for 4.21 cfw)
c. can't make your own cheat pkg for some games like final fantasy XIII-2, console goes to recovery mode
what's good with 3.55 CFW is that after decrypting games for higher fw, you can encrypt them with 3.55 keys to make them work. You can also do that with darkeboot fixer 5.0. so absolutely you can make any games work in 3.55 now as long as the keys to decrypt the eboots are available. if only homebrews like codeunique will be updated to 4.21, i will install 4.21 REX immediately. but i have read that codeunique can't be updated since it's a hacked app based from ps3usercheat. so it's a closed application, but let's hope Oct0xor and Flat_z can do a workaround to update the homebrew.

Now i get it,i didn't know about this homebrew,so this codeunique you metioned is just like a game shark for ps2 to enable cheats.But no problems at all about that and the cheat pkgs , because i never use cheats.
I'll just complete my old Psn games for 3.55 and then i'm definitely going to install 4.21 REX , no more doubts.
Thanks for the help.
