Tema: Entrando a mail, aparece la pantalla 1 segundo y vuelve al menu inicia
bueno, esta vez es una solución y no una consulta, lo busque en el foro y no lo encontre.
aparentemente se da con la versión 1.1.4 y alguno de los desbloqueados (yo lo hice con iplus made by bart)
la solución que me sirvió fue la primera, ingresar por ssh y cambiar los permisos de la carpeta mail a 777 pero también anexan otra. bueno los dejo con la solución y la fuente.

A number of users who have upgraded and jailbroken 1.1.4 are reporting that the Mail application stops working properly after the upgrade and/or jailbreak is complete. These reports of a broken Mail.app come in a variety of forms. For some users, Mail crashes when they attempt to open it. For others, it simply fails to download any new messages. Still, for others, Mail crashes when attempting to read a message.
Regardless of the particular symptoms your Mail is experiencing, should your Mail.app be broken after upgrading and/or jailbreaking 1.1.4, here are some possible fixes:
Fix permissions on your mail folder
1. Via SSH, or whatever method you prefer, connect to your iPhone and enter the filesystem
2. navigate to /var/mobile/Library/mail
3. set permissions on your mail folder to 777 (via 'chmod -R 777 *)
Install SyncFix via Installer.app
1. Open Installer and add the iClarified source (http://installer.iClarified.com)
2. Install SyncFix (under dev 1.1.3)
Perform a Restore to fresh 1.1.4
If all else fails, try throwing your iPhone into Restore mode and upgrade to a fresh copy of 1.1.4. Users are reporting that when all else has failed, they were able to get Mail working again by restoring their iPhone.
Be sure to make sure your iPhone is fully backed up before restoring.
