My first cell phone was a Samsung x427m. I got it in January 2005 and it still works. Gonna give it to a friend who needs a "new" cell phone. I got it for FREE from Cingular. It's so old, you can't get onto the internet with it. It's a great BASIC phone. I logged 22:17:16 of talk time in 14 months.
My second phone is the one I'm currently using which is a Sony Ericsson Z520a. I got it in March 2006 because I wanted a Bluetooth phone which could take advantage of my then-new car which had a hands-free feature. Bought it for about $100. It has an internet feature but it's really slow and crappy. Using the other applications like the calendar and memo pad is a joke. As of today, I've logged 58:40:13 of talk time in about 27 months.
