This is an obscure, possibly hardware dependent error.
I have a webview that is trying to display a twitter feed like this: http://twitter.com/HP
The view works fine on a Droid 2, but fails on Droid and Droid X.
Instead of displaying the page, it just displays the twitter logo and hangs forever.
about the devices:
All running the same software, and Android 2.2. However, they are running different flavors of Android 2.2. Droid X: 2.2.1 Droid 1: 2.2.2 Droid 2: 2.2
It seems that Verizon must have added a bug or fixed a bug in their later versions of 2.2.
