You don't have a gamerscore but depending on the achievements you have you get trophy levels.
No
You can not because PlayStation Network and Xbox Live can not interact with each other. Also PS3 can not go on Xbox Live using a PS3.
first it is not ps3 live it is psn (playstation network) no it can not if ps3 were Microsoft or xbox were sony it would be possible
You don't actually get Xbox Live on a PS3, the network for the PS3 is called the PlayStation network (creative). To connect you need an internet connection and a membership. I am currently on the XBox 360, so the details of how to connect aren't my area of expertise...
There is no way. PS3 users play on "PlayStation Network". XBox users play on "XBox Live".
No. Live is a term for the Xbox and the Playstation Network is what PSP and PS3 users have for online games and more. There are no PS3 Live servers only because Playstation has the Playstation Network and Xbox has Live PS3 is owned by Sony, and they have their own servers. XBox is owned by Microsoft.
iv got an xbox 360 but i think ps3 is better.
no
Xbox is paid live, as the PS3 is free online. Both consoles have exclusive games. Xbox has DVD's, PS3 has blu-ray disks.
