Nokia E52 — what a %@% phone

i have the nokia e52. What a piece o junk. I upgraded in feb and have already sent my phone 2 JHB to replace my speaker. Not only is it a NEW phone,but the signal SUCKS,it freezes up every 2 minutes,i switch it off i have 2 set my WALLPAPER everytime. I have used NOKIA for the last 15yrs. Im unsattisfied with your new phones. I am a bussines man and cannot afford going without my phone. PLEASE have this sorted out.
