Per the title, there are new versions of Maps and Street View in the market. The Maps update is just to add walking directions I think, and the street view was a more polished update. Street view doesn't work after install, at least on my Epic. I open maps, pick a road and long-click on it. A balloon pops up saying "Loading address" for about 30 seconds then give me a pop-up error that says "Data Connection Lost, Retrying" But, data is working just fine on the phone everywhere else. edit: Try rebooting the phone after install, it helped. Still some errors but much better than before. It is awesome when it works. Try compass mode.
