I am with network3 and they supplied me with a sony erricson witch I didnt like so I bought a nokia X6 from a freind witch was origionally on the vodafone network. I popped my 3 contract sim in and it worked great! I could connect to the internet no probs, even watch youtube videos with great sound etc. After a couple of weeks, I can access the internet but, even though I get to the you tube site; when I select a vid to play It says cannot connect ?
3 have sent new settings to the phone now I have 8 "I think" but still I cant look at youtube vids! It worked 100% for a couple of weeks and there is no problem with the network as I have tried the sony erricson and that gets the vids no probs. help Please.
You could try to download the latest youtube app from http://m.google.com to see if that solves your problem.
Or bypass the apps altogether and visit http://m.youtube.com using the phone's web browser. That site is optimised for streaming to mobiles.
Also check that Real Player has the correct access point set for streaming video.
Menu > RealPlayer > Options > Settings > Streaming > Network > Access point in use
This really is a big failing imho... you have to change a deeply buried setting for video streaming every time you use a different network to access the internet.
