Today I submitted version 1.4.1 of MyShop and MyShop LITE to Apple.
The most important change is that it now supports stores with double authentication (standard osCommerce and additional .htaccess authentication).
I hope that it will be released soon.
Have fun!
Update 2010-03-02: The App is now available at the AppStore!
is this going to be available in the US store again anytime soon? It seems to have been pulled form it as of today (3-30-2010)
Yes, I had to remove version 1.5.0 because of a bug (http://bugs.malorny.net/view.php?id=66). The fixed version 1.5.1 is already submitted to Apple and will be available in a few days.
