Transferring files from mobile to pc without cables or bluetooth device?

If both devices have infra red you can use that.

Bluetooth is the only way I know of apart from emailing. If your pc is not bluetooth capable you will need to get a "Dongle" from a local phone or electroncs store, ( it is smilar to a flash drive). then you have to set up a partnership between your mobile & pc. same as you would fo a handsfree device. Once that is all set up it is just a matter of selecting a file on the pc (usually from documents not the program) right click on the file and select " beam to device" then it will ask you to select the device from a list, select your mobile and go ok. The phone will ask if you want to accept this file, go ok and its done. phone to pc may require info from the instruction book because they differ slightly, but just try going from the program and selecting menu etc.

Cable is the fastest way, and bluetooth the next. If you want to use other method, you need Internet connection, then send/receive file to/from phone using instant messenger application through the Internet, but it will be very slow and costly.
