Hi - I know this is unrelated to the thread but I just wanted to share a solution to a problem that I had with my w810i...
I was trying to get the PC Suite to detect my phone when I plugged it into my USB hub, but despite installing it a few times and reinstalling the USB drivers etc it kept saying "No connected mobile device found". Googling this error message came up with nothing - so hopefully now it will help someone to read that I simply fixed the problem by plugging my phone directly into the USB drive on the laptop - rather than through the hub. Now the phone works when connected through the hub so there you go - sorry for disturbing you!
