just an FYI, i updated the package on my site(s) a week or so ago with the new versions. its packaged with a neat ALX installation (optional for each theme for all 7100/7200/7500/7700 series). OTA installation is available as well. see the sticky in the 7100 series forum.

i will note that none of the themes' file sizes changed from 4.0.2.36 (packaged version previously available) to 4.0.2.49 except the Vodafone 7100 series and the 7700 large icons themes.
