Mail client that stores all mail on device?

Anybody know of an iOS mail client that would store my whole inbox on the device? and have it searchable?



I run an online business and get thousands of emails a day. Makes it really hard to sort out on my phone. As it gets stuck accessing the server.



Anyone know of a client that would store all my mail on the phone itself? Or even a JB tweak maybe?



Thanks.
