Here is a note from regarding a bunch of iPhone applications:

Very soon applications such as snes4iphone, gpSPhone,, 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!
