Yeah. Data works fine. What i meant was, as the Iphone does not have mms support & O2 PAYG do not support e-mail, i have no way of sending pictures from the handset
I played around with this and discovered that you can use email on Pay and Go, but only an O2 email account as it will only connect to O2's mail servers. Register an account on o2.co.uk and then set up your email as a POP account with the following:
Incoming
Host Name: mail.o2.co.uk
Username: <your username>@o2.co.uk
Password: <your password>
Outgoing
Host Name: smtp.o2.co.uk
Username: <your username>@o2.co.uk
Password: <your password>
This should work okay over EDGE/GPRS, although their mail servers do seem to be pretty ***** and are always timing out or just refuse to accept my username/password.
Alternatively, you can use any other email account and substitute the outgoing settings with the ones above. You will only be able to receive new mail with Wi-Fi, but you should still be able to send with EDGE/GPRS as you will be using the O2 mail servers.
