I bought T230 for my wife as she was use to T310 and she wanted a colored display phone in reasonable price.
I got this phone for 5K.
Phone is good and most of the features are same as T310 which I have (Except the IR port, joystick)
The pros:
Color,
Cute size and looks like ladies phone
Voice recorder and recorded voice can be used as ring tone.
Polyphonic ring tones
fast dial
Computer connectivity via cable
Cons:
memory available is not good enough for bigger images/many ring tones
speaker is not powerful enough so in traffic noise its barely possible to hear the ring tone.
The key are little inclined at one side....I could not understand why it been done.
No IR port
2 band phone
I thinl Nokia would be a better choice, as battery life is real bad for this phone. Also this phone has shown some bugs in software and it shows full battery even if the battery has got discharged completely.
