I am using the LG KP105 Cell phone after I lost the trusty one that was from Samsung. It is not that user friendly and that makes me piss off. Anyway I got to be a miser due to the recession.
Pros:
CHEAP.
No Camera
FM Radio
Calendar/Memo/Alarm
Sudoku
Battery lasted 6 days with light usage of SMS and talking
Cons:
FM requires headset
Can't do other stuffs (like SMS-ing) while in FM mode
Keys are tough to press.
No custom wallpaper/ ringtone
