Thanks so i'm gonna go with voda but if i'm not mistaken 02 has wifi zones throughout the country and voda doesn't.
Wifi > 3G > Edge
if you like to have 3G off to save battery life, o2 is better. If you like to use 3G Vodafone is better as edge isn't so good!
I was on o2 with the iPhone for 18months, and then with Vodafone for 7.
As for calling, never had a dropped call on Voda, happened several times on o2.
Generally i prefer Vodafone as I can use 3G on the tube on my daily commute. I turn 3G off whilst at home and at uni to save batt. Hopefully with the iPhone 4, the battery will be better so 3G can stay on all the time.
Does Vodafone have coverage on London Underground?![]()
Nope!
london underground, is above ground in many areas. I travel from zone 4 to zone 1 and only zone 1 is underground on the picc line.
Ah, I thought you meant in Zone 1 - that'd be impressive!!
