After being impressed by Open Mini 4 Beta 2 on a HTC Vox smartphone, I decided to try it on another Windows Mobile 6 smartphone: The T-Mobile Dash (HTC S620). The Vox has both a QWERTY thumb keyboard (pull out) as well as a standard numeric dialer layout. The Dash, on the other hand, just has a QWERTY thumb keyboard (my favorite of the various thumb keyboards I’ve tried). Opera Mini seems to place the keyboard in numeric keypad mode when in browse mode because I was able to use the 2-4-6-8 diamond pattern embedded in the QWERTY keyboard layout to quickly navigate around a web page. The Dash has a very reasonable square layout for the numeric keypad on its keyboard. The Vox, on the other hand, has a slightly asymmetrical keyboard layout that makes navigation a bit harder.
CNN.com was still unreachable (although alive from any other device I tried). But, other sites I tested looked and worked fine with Opera Mini.
