Finally, I have some time to share my results of testing YoWindow on my HTC Wildfire S (Android 2.3.3).
The most important that if the weather is overcast then YoWindow shows a black screen and force closes immediately. In settings menu weather update 'button' is not working, instead of it the units of measurement open, and instead of the units the vote for YoWindow opens.
However, I know that YoWindow is not entirely compatible with older devices, but another functions (sound, wallpaper, user interface, parallax effect) work quite well.

One suggestion at the end, would it be possible, if I connected to the Internet, then YoWindow refreshes the weather automatically, for example in the notification bar and in the widget. Most of other weather widgets are not able to do this...
Keep good working,
Adrian
