Hi Claudius. My WinXP Skype client is on the last but one 4.2 release (it's telling me to update to the new one). I have the webcam set up and working on the PC and have logged into Skype with a different account to the one on my N900. Both accounts are showing as being online to each other. The N900 doesn't give the option to make a video call unless the local status confirms the remote Skype account has a webcam available and is online. I can initiate a video call from either end, but the N900 doesn't seem to turn on it's own cam by default - you have to click it. The video call option only works in landscape mode.

But back to the original question. Anyone got Skype video calls working over UK T-Mobile 3.5G?
