Lost My 3g Internet since Froyo upgrade

[Guest stefor]

Hi All

My HTC Wildfire was bought as a Vodaphone but unlocked. I use it on the Orange network.

pI received the over the air upgrade to Froyo a few days again. Been using it since the upgrade using the WiFi and everything has been fine. On leaving the house it usually automaticaaly turns on the 3g, but now doesn't seem to change and just says "No network connection, Browser cannot load this page because there is no internet connection". Looked in the settings and everything seems ticked and still got Orange as my mobile network.

Has anyone got any suggestions?
