Turn Mobile Phone into Webcam

I found two softwares that are compatible with my Nokia N95 8GB to use its camera as a webcam on my laptop. WWigo is freeware, but only allows for bluetooth connectivity which i do not have. I also found some software called Mobiola webcam, which allows use of bluetooth, usb and wifi connections, and it costs $19.95. I didnt know what would be better to invest in, a bluetooth dongle ( i dont know how fast data transfer would be), or in the software that allows me to use a usb cable. Can anyone offer me advice on this? Thanks in advance

 

I tried out Mobiola with its 3 day trial and it seems pretty good, but there is some delay between moving the camera and this appearing on screen. This might just be because of slow transfer of data by the USB cable. Im still not sure which to go with. Does anyone have either of these softwares?
