I had this start happening to me today.Guys I thought I read about someone having data issues with 4.5 but can not seem to fina a solution. Anyways I am having problems with my data, not working, 4.5S, I get an error message that says
Cannot Connect
Dialed:
"Cannot connect for an unknow reason. To check your connection settings...."
I have tried hard resets as wells as reflashing, cant seem to get the data to work, any suggestions?
The cause was because I had installed the remove hidden proxy cab.
As soon as I put the restore hidden proxy cab back in, pIE started working again.
