Does OS4.0 provide this via the handheld software, or via BES/BWC upgrade? In other words, if you are lucky enough to be beta testing the Handheld 4.0, can you view images and use the Picture app., or will you have to wait for a BES/BWC upgrade?
As for the open source app., take a look at these links...they walk through Klaus Thiel's Screen Saver application, and the many issues that many of us had before we got it to work. One very nice feature Klaus added was breaking the program into two modules. The one that accesses the restricted API does not have to be modified at all (he had it signed, and any changes would need to be signed again). The other module, containing any images you add/cahnge, does not use the restricted API. Very very cool!!! http://www.blackberry.com/developers...863&q=#top http://www.blackberry.com/developers...amp;msRange=30
Feel free to ask any questions -- I have gone through about a gazillion permutations to get this to work, and am pretty familiar with all the necessary steps.
