T619 Web Settings

To set the default web page for Samsung T619 with T-Mobile,

*#87927# to get into the Browser Settings area
Navigate to Profile Settings and open an empty profile
Enter a profile name
Enter the home url, this is the default url your phone will go to
Save
Navigate to Current Profile and select the new profile

Now when you go to T-Zones, you'll go to this page instead of the T-Zones page. I set it to go to http://3dskimaps.com. Some of the graphics took a long time to load. The user agent was

SAMSUNG-SGH-T619/T619UVFG8 Profile/MIDP-2.0 Configuration/CLDC-1.1 UP.Browser/6.2.3.3.c.1.101 (GUI) MMP/2.0

Of course, you might find it more useful to set it to a search engine like Google.
