Get FIFA13 updates safely

Hey guys,

I'm absolutely new to PS3 hacking scene and just want to know if it's possible to get roster updates for FIFA13 (and other EA Sports titles) safely without risking the jailbreak. The PS3 is in the common room of our dormitory and my roommates would kill me if they couldn't play other games like CoD:BO2 or Tekken anymore :laugh:

Currently, we're using Rogero 4.30 and multiman 4.08.

I do NOT want to play online, I just wanna have roster updates and if possible, some new teams from Creation Centre/Origin.

Hope you can give me some advice.
