→Preventing MobileMail from trying to stay open/autolaunching: Minor clarifications
On this page I describe some Mail-related iPhone OS tweaks. Note that they assume that (1) your device is already jailbroken and , (2) you have installed OpenSSH to browse files on it , and that (3) you have iPhone OS 3.0 or higher on your device. If that's not the case, please [http://blog.iphone-dev.org visit the official Dev team website] for instructions on how to jailbreak your device. Once that's done, open Cydia and install OpenSSH. '''''Please immediately [http://www.iphonefaq.org/archives/97721 change your root password] after you do this to prevent your device from being hijacked.''''' Once that's done, you will need an SFTP client for your computer to browse and transfer files. That is beyond the scope of this tutorial, so [http://www.google.com/search?q=browse%20files%20iphone%20openssh Google is your friend].
==Recovering offline, never-uploaded Mail messages==
#*turn off auto-lock
#*tap your screen every so often
#*or install Insomnia#*plug your phone into some sort of power source (power adapter or USB port)#*(just work very very quickly :))
#Navigate to <tt>/private/var/mobile/Library/Mail</tt>
#Now open the folder corresponding to the email account from which you sent the message (should be self-evident)
You'll notice (if you have [http://code.google.com/p/iphone-backgrounder/ backgrounder] installed and badges for Apple apps enabled) that the Phone app will start but Mail won't. Mission accomplished!
One important caveat: doing this will disable push email, as the Mail needs to keep running for that to work, unfortunately. Mail will continue running after you switch to another app; however, if Mail is quit for whatever reason (using SBSettings, or due to low memory), it will '''not''' automatically reopen until you open it manually yourself. Scheduled email checking will also cease to take place when the app is no longer running.
