My 3g has stopped working

[hard]

Hi today I unlocked my iPhone with the new ultrasnow tool, but I noticed after unlocking my phone to all networks my 3g internet stopped working when I try to acces the net with 3g it's coming up with with a message could not activate cellular data network, and it was working fine before I had unlocked my phone, iv tried to reset the network settings in genral but it dose'nt do nothing.

What network was it locked to?

If T-mobile, did you disable the 3G before Jailbreaking/unlocking?

If not T-mobile, or you did disable the 3G, then you need to call your new network operator & get them to send you the Network Settings via text update.

It was locked to o2 and the 3g was disabled when i unlocked the phone.

You need to call the network you're trying to use.

They will send you 2-3 text messages which will include MMS, GPRS/EDGE & Internet settings.

Once these are installed you should be able to select the correct profile from the settings menu.
