I have been having my Nokia 3120 for the past 3+ years and till date no complaints whatsoever. I have never even thought of changing my phone. Its very simple to use and its worth the money you pay. It lacks features we require now a days like bluetooth, camera, radio etc.It has 128*128 color screen with good resolution with GPRS enabled.
You can download colorfull wallpapers, screensavers and polyphonic ringtones. In built ringtones are just amazing. Even today when my phone rings, people starts staring! A feel of a proud owner.
