I just got my evo yesterday and have been looking for an answer on how to get this widget as well. I'm pretty sure its weather and rss feeds and I have seen it on the nexus one but it is no where to be found on my evo or in the app catalog.
well i just found a download for it.. google "droidlife" and it should be the first one. then go to downloads and its there.. i got it on my g1 and it works fine . thanks anyways guys
