Right,
It appears there is something cocked up in the voda firmware install that's affecting the internet conectivity of the phone for some users,
if you have this problem
Try a full reset
type *#7370# into the dialer, this will Reformat your phone but should not remove maps and the QT enviroment
this has helped some others with voda handsets and a similar problem
note you will probably have to start the phone setup from scratch
Note I do not work for voda, My advice comes from experience and my opinions are my own
