Why do I get an "Attention required. Press here." message when I try to download an application or game?

This can happen when you're trying to download a large application or game - generally 20MB and over.If you are downloading anything from the Marketplace that is larger than 20MB you will need to download them via a wifi connection.
To finish downloading and installing your application or game, try the following:

• Make sure that your phone is connected to a WiFi network.
• From Start, press Marketplace
• At the bottom of the screen, press Download to see the queue of incomplete downloads.
• In Downloads, press and hold the application or game which is stuck and then press Retry.
• The item should resume downloading. Once installed, an application will appear in the Applications list. Games appear in the Games Hub.
