I'm using a Nokia 3200... currently priced at around P9,000 at Greenhills.

has most of the features most people are looking for in a celfone these days:
-tri-band (I went to europe for almost a month and also stopped over at hong kong, no problems).
-color display
-polyphonic ring tunes (true tunes also if you can convert wav/mp3 files to its native format)
-digital camera (a bit limited but functional)
-customizable case
-flashlight
-infrared connection
-gprs capable
-very loud speaker
-fm radio
-voice recorder (you can record your own ring tunes)
-battery is good for 3 days (with vibrate on and some voice calls)

downsides:
-weird keypad (but I got used to it in a couple of weeks)
-limited memory (1 meg, not expandable)
-can not take video clips
-screen display quality is inferior as compared to N6230.
