TO SET UP AN iPhone so it can use Vodafone Ireland's network, you need to go into Settings> General> Network> Edge and enter three fields. The ISP APN settings are as follows:
APN: isp.vodafone.ie
Username: vodafone
Password: vodafone
We use these settings to get the best cameraphone in the house (at left) sorted for data purposes. Prepay customers are charged 19 cent per MB when using Vodafone's network for this.
