A note about Memory:
The following features may share memory: contacts, text, graphics
and ringers, calendar to-do notes, games, and applications. Use of
one or more of these features may reduce the memory available for
the remaining features that share memory. For example, saving many
calendar notes may use all of the available memory. Your phone may
display a message that the memory is full when you try to use a
shared memory feature. In this case, delete some of the information
or entries stored in the shared memory features before continuing.
Some of the features, such as ring tones, graphics, and applications
may have a certain amount of memory specially allotted to them in
addition to the memory shared with other features.
