These instructions assume you are running iPhone OS 3.0 or above.
 The app to use on the iPhone is called MobileTerminal and it’s available for free in the Cydia store.
, You’ll be prompted for the ‘old’ (current) password for the mobile user. Enter this as the old password: alpine

, You’ll then be prompted to enter the new password – so just type in your desired new password. Use good password principles if possible (long and strong). You will not see characters appearing on the screen as you type – that’s normal, not a concern.
 You’ll then be prompted to re-enter the new password. Do that.


You should then be returned to the Mobile$ prompt that you started on when opening the MobileTerminal app. There’s no success message to say the password was changed – but if you’re returned to the prompt and do not get an error, the change was successful. And you’re done with change for the mobile account.


Enter this: alpine

;
,,,
Make sure you have the right version.
Get your app.
Once you have MobileTerminal installed, launch it and you should see a prompt saying this or similar:


iPhone Name: ~ Mobile$
At that prompt, type: passwd

,
Enter in the old password.
Enter in the new password.
Re-enter the new password.
Type this to switch to the root user: login root


You’ll be prompted for the root user’s current password.
Type this to start the password change routine again: passwd

,Enter the old password for root (it is ‘alpine’, same as for the mobile user) and enter your desired new password twice, just as you did for the mobile account

,
Done.
