(adsbygoogle = window.adsbygoogle || []).push({}); 1. Can i jailbreak a brand new PS3 slim??

2. If i sign in to PlayStation network with a jail broken PS3 will i get band/Bricked??

3. Say i unlock 200 trophies (on a Jail broken PS3) then decide to update to firmware 3.66 will i loose the trophies i got while jail broken??

1. if u jailbreak u must be on 3.55 or lower and you cant sign in without getting bricked so you must be on 3.66 firmware to sign in without being bricked although people are working on a 3.66 jailbreak its best to be on 3.66 and wait for the jailbreak

For number three I would probably say yes. You might lose them all.

so just wait for the 3.66 jailbreak but no u dont lose them all u lose 96% of the trophys but u keep the rest and then wen the 3.66 cfw comes out we will have everything again
