iPhone SQLite Database Structure

Note: Before you continue, you will need to install sqlite3 package from Cydia.

Note: The following guide assumes you are logged in to your iPhone using an SSH client. Google: iPhone connect via SSH

iPhone uses SQLite3 databases to store most of the important data, which you can easily view/modify/manage using sqlite3 shell command.

The main databases are:


So, if we want to see their structure/contents, we can run a simple sqlite3 query from shell:


To get the tables contained in database "Envelope Index" (our emails database):

iPhone# sqlite3 /private/var/mobile/Library/Mail/Envelope\ Index

SQLite version 3.6.12
Enter ".help" for instructions
sqlite> .tables

mailboxes messages properties
message_data pop_uids threads

To see the table structure of table "messages":

sqlite> pragma table_info(messages);


To get results of email messages that are not read, not deleted, ordered by descending order (latest first) , limited by 5 (5 latest results only):

sqlite> select * from messages where read='0' and deleted='0' order by ROWID desc limit 5;

To delete (permanently) the email message at row index 123:

sqlite> delete from messages where ROWID='123';

To change the message subject of the email message at row index 87:

sqlite> UPDATE messages set subject='sqlite test' where ROWID='87';

A similar usage with Objective-C / Cycript:

[[MailMessageLibrary defaultInstance] messagesMatchingQuery:@"select * from messages where read='0' and deleted='0' order by ROWID desc limit 5" options:nil];

Post here any comments or questions you might have on the above.

Excellent work! This was missing from like...everywhere.
a question: how can I access AddressBook\'s pictures?
There is a db AddressBookImages.sqlitedb which seems to store the contact\'s pictures.

Posted on: 01-03-2010 11:17 by Elias Limneos

iPhone:/User/Library/AddressBook root# sqlite3 AddressBookImages.sqlitedb
SQLite version 3.6.12
Enter \".help\" for instructions
sqlite> .tables
ABImage _SqliteDatabaseProperties
sqlite> pragma table_info(ABImage);

You will see that the data fields contains images in binary format. To see them you will need to open this data as image.
I will post a guide as a seperate chapter here, as well.

Hi Elias.

Sorry for using this space, but could not find a more appropriate one or contact-info.

I just installed Cydget Element. THANKS for your work on that.

Based on replies of others i read, and on my own experience, i wonder whether there will be a next version, and whether that will include:

- having the choice of only choosing unread sms, instead of all
- having the choice on what number of calendar events are shown (like with SMS, email etc)
- having the option to shuffle/re-arrange the element-parts, so for instance you can show calendar events before email and sms

Anyhow, again: thanks for the app!!!

Hello, I made transaction o Jan 03,2015 number 2UY46774AM9769626, but it does not work on my new iPhone. Can You help me?

Posted on: 09-02-2016 21:54 by Jim Brill

Hi Elias,
Your contact page does not work.
I am building an app that will save hundreds of thousands of lives each year. I need your assistance to do some of the programming for a Jailbroken iPhone to demonstrate the app. It requires some of the same programming you used to create your impressive call recorder. I will provide more detail in private. I will be happy to provide substantial compensation.
Please contact me at jimbrill@hotmail.com
Thanks, Jim Brill

When are you going to update all the jailbreak tweaks?

Thanks for providing the iPhone SQLite Database Structure here. I had been searching for the various databases used by iPhone to store different data. With the source code we could actually modify or manage it using sqlite3 shell command. wholesale tablet
