Nokia N75

I've had this phone for 4 days now, and i i really like it alot, it had a lot of good functions, but i have a little problem with the reception, when i hold the phone while texting i hold the back of the phone (bottom part) and my reception seems to drop always to almost one ar or nothing, and also while im talking sometimes, it does the same thing. does anyone else have the same problem, im just wondering if it;s my phone and or what ? also when i try to transfer music to the phone, im having a hard time trying to rename my track tittle and album ( Nokia Music Manager) doesn' allow me to edit anything, only scan my computer for tracks and then transfer them to the phone ? I'm not suew what im doing wrong here. If anyone have any ideas pleas...
