I was using Shozu to upload pictures and videos to flickr and youtube using my Nokia E61i. It is a really cool application and I had talked about it earlier when I had installed it on my earlier phone.
When I finally bought the new phone I was missing this application as currently the Samsung i780 is unsupported and I was unable to find a version that I could run on it. After trying out a few versions I stumbled upon the HTC Touch version and it works quite well on this phone. So if you have a Samsung i780 download the shozu application for HTC Touch and use it. Atleast till they provide support for this phone.
