Like some of you here I have a paltry 3 mb of mobile data which I use solely for email when out and about. To minimise the data use on my connection am I better to:
1. Use Pop3 - download headers only and delete all messages after reading OR
2. Use imap - sync headers only and download messages I require then delete all messages off the server OR
3. Use imap - sync headers and download messages I require and leave messages on the server.
I use vodafone email at the moment which states it uses a GPRS optimiser. Does this effectively cut down on data use?
