Sanyo 4920 released today - check telecom.co.nz for specs.
Its $249 (Prepaid Price). 65k colour screen. Very much like the 8100 in terms of UI. Its fat and solid (not a slim small phone by any means).
Build quality seems good. No camera. Has PTT and speakerphone (PTT service not available just yet though).
Nice size buttons, although the keypad layout has changed slightly compared to the 8100. The menu/ok key is off to one side instead of in the middle of the arrow keys. That was slightly annoying, but you would get over it in five minutes.
Nice loud ringtones (almost identical to 8100, with the addition of a couple more)
