Just incase you are not aware, Vodafone's network seems to have failed in some parts of the country.

Not the first time.

We had a speight of a few times a few weeks ago where the data kept dropping on. Very annoying when you are relying a vodafone 3G connection!

I also find the coverage pretty poor here too. Seems miles behind t-mobile and three!
