Data settings question

[irishgrizzly]

This may be an Irish/eurocentric question but, I'm going to go prepay from contract on O2 in Ireland. Does anyone know what setting on my phone I can use so it just uses wifi for data?

I can switch off G3, but edge still shows – can this be turned off?

I don't want to be charged whenever I get an email on the road as I have wifi at home/work.

edit your apn so that it cannot connect to the data service. its in settings - network somewhere. just add a character to the end of the existing addresses.
