Shared memory
The following features in your phone use shared memory: Phone book, text 
and multimedia messages, images and ringing tones in gallery, calendar 
and to-do notes, and Java games and applications. Using any of these 
features leaves less memory for other features. This is especially true with 
heavy use of any of the features. For example, saving many images may 
take all of the shared memory and your phone may display that the memory 
is full. In this case, delete some of the information or entries reserving the 
shared memory.
The following functions use shared memory that is dependent on the data 
quantity per item and shared memory available at a time in the Nokia 6610:
• Phone book (up to 300 entries)
• SMS messages (up to 150 text messages or 50 picture/concatenated 
messages)
• Calendar notes (up to 250 entries)
• To-do list (up to 30 entries)
• Fixed ring tones (11 preset, not removable)
The following features share a memory pool of 725kB:
• MMS messages (max size of 30 kB per MMS message)
• Ringing tones in Gallery (20 preset, all removable)
• Images (10 preset, all removable)
• Java applications (3 preset, max download size 64kB per application)
