How do you get your mom to give you back your cell phone?

Well Honestly I Have Been Punished Numerous Amounts Of Times. As A Matter Of Fact, I Am Punished Right Now, I Dont Have My Blackberry And My Blackberry is My life. I Got Punished For Having A Facebook When I Wasn't Allowed To. I Have Learned That You Have To Genuily Show Your Parents That You Have Matured And Grown From The Situation And Are Willing To Put The Past Behind And Work On A Better You. Help Around The House, Help Your Parents With Things That Seem to Be Burdens on Them. Whatever You Do, DONT STOP
