I'm new to this, I ordered a pandora battery and still have to get a larger memory stick before I install CFW, but after reading the tut's on installing, I had a question, Would I be ok to install official 4.05 until i'm ready to install a CFW? Using the playstation network to play demo's it says I have to have a new FW have them install and play. I currently have 3.80 out the box. I just don't know if it can be installed if it shows that files are up to date or if it just forces the install of CFW in service mode. Thanks!
