Lots of maps but most of them won't display

It is slow and crashes a lot, but since ESRI's JavaScript API does not work on WP7 this is your only choice. I had to uninstall it because the app would not open any more. Also, it would be nice if it supported all of the functionality found on ArcGIS Online.

Great collaboration app!

It's great... I just don't know what exactly it's supposed to do... I'm sure if you know though, its a wonderful product. Map clarity is good good and response time is quick. Honestly though, if you're looking for a "Oh, hey, there's my house!" app, this is it. That's all I could tell that it would do. Show you your house.

At this point this is a "neat toy". While it does connect to my ArcGIS account and show me my groups and maps, it will not permit my maps to open on my phone. I cannot find any way to get assistance with this. For this to be a truly helpful, useful app, it needs to be cross-platform where I CAN access my maps from both my phone and my desktop. Once this is fixed, the app will bump up to 5 stars.

This is THE mapping API for WP7. Even puts the built in maps app to shame. Developers, learn more at esri.com/windowsphone Edit 10/12/11: thank you for adding custom server URLs, now we can use this for the company.

Maps never load.

The new update makes this an awesome map for browsing all sorts of maps and data around the world. Literraly thousands of maps available, and you can even make your own mashups via www.arcgis.com for free!

Very nice mapping tool

Can't wait for the next version release toward the end of this month =D
