How to Load More Messages on an iPhone
One of the biggest benefits of the Apple iPhone is the ability to receive email messages just as though you were sitting at your home computer. An iPhone can be configured to fetch email from just about any service that offers POP3 or IMAP capability. Configuring your iPhone to receive your email is a simple process that takes only a few moments. By default, email boxes are configured to display only the 50 most recent messages. You can easily update this setting to allow more email messages to be displayed at a time.
