No 3G on a Samsung GT i5800 I recently bought a Samsung GT i5800, ok. It has Android 2.1 update1 installed. ok.

If i need to connect to the internet through wifi, then i can, ok!

If i need to connect through a vodafone mobile internet connection, then i just can't!! What could the problem be? I tried to reset the phone to factory settings, and then power off, power on, then enter PIN, then? it should work, no? Why does it say's "the page cannot be displayed"? why isn't working?:O

Are there any tips? Can i provide you guys with more info? [what info?]

:( please help!
Check that the following setting is ticked:

Settings->Wireless &amp; networks->Mobile networks->Data enabled 

Also verify that the access point name settings are correct and the correct access point is chosen. You should be able to find the details of what it should be on the Vodafone website. The settings are at:

Settings->Wireless &amp; networks->Mobile networks->Access Point Names
