The Nokia Store backend has been updated on 03.11.2011 and this release of the client is fully integrated with the backend release
Fixed: ‘Debug’ option in the client has been removed. This was meant for the R&D team. Sorry for the confusion
Solved: Purchase option for Symbian Belle users
Theme Pack (Gift Package) feature is available for Nokia C7 users

This feature will offer a collection of premium applications at no costs to the selected users for a period of time, e.g. 30 days
In the Store application, the users will see the Theme Pack banner on the home view. Upon clicking on the banner, they will be linked to the Theme Pack collection
