This may seem like a stupid question, but I just got my X and there's a pull tab inside the battery cover thats connected to something that says do not cut. I pulled lightly and it didn't come out. I just wanted to make sure that I'm supposed to rip it out or if I should leave it alone. Thanks.

...Now I need someone to tell me how in the world I'm gonna get that battery out again! Don't tell me I've screwed it up already!!!
Please tell me there's a way!
