I switched to Sony Ericsson after Nokia 6600 and 7610, the Sony ericcson was always the best for me I loved the Walkman,camera and the design of all phones that I used but then i waited so long to buy a perfect device with the best technology, to feel better when ever i use it. So sad i was impressed by Nokia N900. No folder option , no portrait mode , lack of apps... Iphone 4 is the best to wait for.
