* Shared memory
The following features in this phone may share memory: (phone book, text and multimedia messages, images and ringing tones in gallery, calendar, to-do notes, and Java™ games and applications). Using any such features may reduce the memory available for any features sharing memory. This is especially true with heavy use of any of the features (although some of the features may have a certain amount of memory specially allotted to them in addition to the amount of memory shared with other features). For example, saving many (images, bookmarks, java apps, etc.) may take all of the shared memory and your phone may display a message that the memory is full. In this case, delete some of the information or entries stored in the shared memory features before continuing.
