iPad mail keeps loading older and older messages - I have got an iPad 2 and set up Gmail. Every time I open mail on my iPad, it keeps loading older and older messages. But I have set iPad Mail to 'delete from server when removed from inbox'.
To prevent getting old mail, login Gmail via a web browser on your computer. Click Settings > Forwarding and POP, and then select "Enable POP only for mail that arrives from now on." under "POP Download".
If you only use POP account on your iPad, this can prevent the iPad from downloading older mail.
