I have had a couple of problems with the 3G just not connecting, so I have to go into the Network settings, turn off 3G put the phone to sleep then wake it up, turn on 3G again, put it to sleep AGAIN and then it will work.
Which is a right pain.
Although today it just got alot worse. At about 4pm I was unable to view any pages over my Vodafone data connection despite my above troubleshooting.
Also when I got home and connected my my Wi-fi connection (which I have had no problem with on the iPod Touch or iPhone before) shows the little Wi-Fi icon in the status bar up the top but will not get a connection.
When I go into Network> under the VPN it says "NOT SET" is this correct?
Anyone got any ideas of what could be causing this, normally I would call Vodafone Customer services but this is after hours.
