Sketches 0.7 continues to be compatible with iPhone and iPod Touch devices running firmware versions 1.0.2 through 1.1.4.
Firmware 1.1.3 introduced an important change: third party apps no longer run as the root user, but as the non-privileged mobile user, meaning that most of the file system paths have changed.
Sketches will deal with platform specificities and will automatically identify and adapt to the device and firmware version it is running on.
