Keep more than 200 Mail messages
I've been an iPhone user for years, and I still haven't quite figured out if this is possible or if there is an alternative Mail app that makes it possible.
I'd like to be able to keep more than 200 email messages stored LOCALLY on my device without having to "load more messages from server," and be able to view them offline.
Anybody have any suggestions on how to do this or of there are any apps out there that can do so and are decent?
Thanks for any input!
