I just found out that the HTC HUB v2.5 seems to work on non-HTC wp7-devices. I installed the xap with the Application Deployment(just a try) and everything works aside "featured" (It loads and loads but shows nothing). I had no bugs or crashes aside that and thats a good thing I have a LG Optimus 7 with the newest mango (vodafone update) from germany!
Here is the xap that I used: download from rapidshare: https://rapidshare.com/files/1655221517/HTC_Hub_v2.5.0.0.xap
Maybe someone can try to install this on some other devices! It may works
Is the live tile also working?
