which phones have volume control???

hey 7210, 3100, 5100, 6100 which 1's have volume control __________________ Only the 3100 doesn't have a volume control on the left hand side of the handset. The 3100 has volume control with the up & down buttons. __________________ i.e. ALL Nokia have volume control. In fact all mobile phones have that (i don't know every phone, but that just seems like a must have) __________________ wen talking on the 3100 u can set the volume by using the right and left keys u can also use this while listening 2 ringtones or while on loudspeaker __________________ Im sure they all would have some sort of volume control, its a pretty basic feature __________________ Yeah, even N5110 has volume control, and you all know how old that phone is...
