PLEASE HELP ME WITH MY CELL PHONE IM DESPERATE?

So i have a stupid Samsung Reclaim (i hate this phone, it has bad graphics, and volume, and picture, and just everythimg sucks.) Anyways, I didnt even get to pick out my phone, as my mom got the cheapest phone through this really cheap awful Bell plan at her work. Anyways, my brother is getting like a f*cking blackberry (hes my twin) for his graduation present, when i got mymphone dor my burthday in may LAST YEAR. (2010). Im really mad. Also, for some reason, my phone will NOT show my sent messages ever since 6 months ago. Is really irritating forgetting what i text the person if they take a while to respond. Also, my phone is SO messed up thatmit sometimes freezes for no reason, and i sometimes dont recieve peoples texts. So they usually are texting me for like 5 hours then at midnight i get a text from people saying "wow thanks for ignoring me." And i cant live with this phone it drives me insane. Please help me to convince my parents i want a new phone for MY grad present too?
