Yes I do have a cellphone. I currently use a BlackBerry Bold 9780 as I have a hard on for BlackBerry. Here is my history of using cellphone and I'm gonna try and do this chronologically and as accurate as possible:
November 2002 : Almost bought a Nokia 3310 but changed my mind at the last moment as I didn't have the money
July 2003 : bought my first cellphone, a Motorola T190. Very solid but not user friendly at all. Black and grey screen.
March 2004 : Bought a Samsung R220. Nice phone.
September 2004 : Sold the Samsung and bought a Nokia 1100 (the made for India phone)
October 2005 : Bought my first colour screen cellphone - a Sony Eriksson K500i. Colour display, camera, GPRS & MMS. Had solid sound playback but very limited storage space.
June 2006 : I wanted a flip phone so badly and got the Motorola Razor V3i. Loved it so much.
April 2007 : No idea why but I sold the Razor and got a Samsung SGH E250. It was an ok, slider phone but I have no idea why I sold the Motorola.
November 2008 : The Samsung SGH got damaged after I tripped and fell on the railway tracks and I got a Nokia 2600. I hated this phone but it was cheap and I didn't want to spend much on a phone at the time. I also went through a 'don't care about phone stage for a while". During this time I also used an iphone for 2 months that was in my possession at work. Wasn't impressed.
Jan 2010 : Got my first BlackBerry, the Curve 8320 and I love it still. It's a bit damaged but it still works and I have it in a drawer stored as a possible backup.
April 2012 : Bought my current phone, the Bold 9780. Love it a lot!
