Data transfer from jailbroken PS3 (Rogero CFW) to unjailbroken PS3

Hi all.

I am a noob to jailbreaking. I have done alot of research although it all seems very overwhelming and i have a few questions. I understand the general concepts I think :hmmmm2:

Anyway, I have decided not to JB my PS3 (It needs to be taken apart and have a hardware flasher installed to downgrade to 3.55). I therefore am looking at purchasing a slim PS3 that is JBroken and running 3.55/4.31 Rogero CFW. I was told by the seller that it CANNOT go online. Firstly, Why is this so? And can I do anything to make that PS3 run online (PSN) safely?

If not... I was further informed I can data transfer from the JBroken PS3 to my PS3 if i want to run certain things online (game patches, etc.). Will my unbroken PS3 accept these programs and then allow me to run them online safely?? I cant seem to find any answers on this matter. Also i read if I data transfer from one PS3 to another, the host PS3 is wiped of its content after transferring.

Can someone give me any help or insight please. I really dont want to waste money purchasing this JBroken PS3 if I can't use the patches on it or ultimately play online with them.:questionmark::questionmark:

Thanks in advance.
