Here is a note from zodttd.com regarding a bunch of iPhone applications:
Very soon ZodTTD.com applications such as snes4iphone, gpSPhone, OpenTTD.app, and psx4iphone will be receiving updates to fully support firmware 1.1.3 change to using the ‘mobile’ user instead of ‘root’. There is however a quick fix for those who want these and other applications to work with 1.1.3. You must chmod (set permissions) to 777 to the /var/root/Library/Preferences/ directory and also chmod 777 the directories used for external files such as ROMs, usually somewhere within /var/root/Media/.
More news to come shortly. Thanks for the continued support everyone!
