iSync with LM C375 or similar for Tiger or Snow Leopard

Need help please in finding a mobile to transfer my contacts with iSync to my MacBook Pro running Tiger or Snow Leopard (very soon).

This is what I need, but I don't know the mobile market:

- Unlocked

- Quadband

- Bluetooth

- WiFi

- Dual SIM (if possible)

- If with keyboard, then preferably with keys and not touchscreen

- Facility for a lot of contacts

- Integrated means (or downloadable tool) to enlarge font (or adjust the diopter) so that I can read text messages while wearing contact lenses.

- I don't need music or any gimmicks

- Cost must be much lower than iPhone

Any help would be greatly appreciated. Thanks
