nokia ovi suit

Nokia ovi suit does not seem to run on Mac o/s. and hence to use the nokia hand set for 2g connection through airtel simcard on mac laptop, i have to use windows xp as guest o/s. through virtual box. Due to this the guest o/s. opens in a smaller window which cannot be made into full screen.
Any solution so that the nokia handset model 6300 can be used for 2g internet connection directly on mac laptop without using the windows xp as guest o/s.

I can find no options for what you want on Mac OSX.
I did however find the option to connect your phone via bluetooth.
Setup Internet Connection via Bluetooth using Nokia 6300 on Mac OS X

There is also the option of Bootcamp, but this depends on the age of your Mac.
Bootcamp runs Windows natively on your Mac, thus it will enable you to run fullscreen.

Try and determine the age of your Mac, to see whether it supports dual booting via Bootcamp.
