I need something to backup my mobile phone contact book, send SMS etc. over bluetooth, I tried Soleil software but it does not work on my PC. Is there any other similar software?
I have Windows 7.
For starters, Blue Soleil is a Bluetooth stack and not actually a program for Mobile phones.
You still have a driver for the hardware - but A Bluetooth Stack is basically the layer after this that provides a nice interface and makes the hardware usable.
Whatever Bluetooth stack you use, you need to pair the phone with the machine - then after this, find a good piece of software that allows the features you want.
I cannot really recommend anything over anything else as I have not really studied all the options out there, but I know my dad does pretty much everything you want with Mobile-Master.
