LG Optimus L9 / Optimus 4G

Hello I'm new to this forum and Phone scoop in general. I'm considering buying this Optimus L9. I have the Optimus T but I'm having problems with it. Someone told me if I could root the phone it would be a lot better but I have no idea how to do it I'm looking at zurgrush to see what it takes to do it. There's a lot of pre installed apps that I want to get rid of even on the Optimus l9. Anyway, any input from anybody about this phone or being able to root the phone with a program or app please feel free to contact me

Thank you in advance
James
