Crazy Windows Versions (Mobile)

The other day, I got this excellent new cool toy from InterAccess.nl: the Samsung i780.

But henever I want to download a program I have to select the following distributions:

• Mobile 6.0 Classic & Professional (Not Standard!)
• Windows Mobile 5.0
• Windows Smartphone 5.0
• Windows CE 5.0
• Windows Mobile 2003/SE

Then when I try to install the "right" distribution my "Phone" Windows tells me that it is not a valid "Pocket PC"-application! I thought regular Windows distributions could be confusing but this is crazy!

Try to explain that you your grandmother!
