Ok, take a look at this and see if it follows along the same on your device. It may actually vary slightly, but this may help you do what you are asking. It's not as simple as installing a .cab though.
1)
Download a Registry Editor (you can google it or go to this link
link
To change Default Browser (just for reference) not what you are asking though
2)
navigate to HKCU/Software/HTC/Manila
change value in DefaultBrowserIsIE from "1" to "0"
change value in Internet.SetOperaForeground from "0" to "1"
Registry Edit tutorial thread
HERE IS the Part You want!
For Internet Tab Configuration.
1)
You need to find a xml file located in the following:-
\Application Data\Manila\InternetPortal-en-us.xml
Some people may able to edit this file on their phone, but i prefer to make a copy and put it on my pc so that i have a few backups.
2)Make sure that the
Readonly option has been unchecked for this file.
3) You will see the following when you first open the file for edit. (use notepad)
<?xml version="1.0" encoding="utf-16"?>
<InternetPortal>
<BrowserExe>\Windows\iexplore.exe</BrowserExe>
<IncludeUserFavorites>False</IncludeUserFavorites>
<Banner
DefaultImagePath="\Windows\HTC\Assets\Images\Inter netPortal\banner.qtc"
SelectedImagePath="\Windows\HTC\Assets\Images\Inte rnetPortal\banner_selected.qtc"
Text="Launch Browser"
NavigateUrl="http://m.web2go.com"
UrlText="web2go"
Width="480"
Height="215" />
<OperatorLinks>
<Link
Text="YouTube"
Executable="\windows\youtube.exe"
ImagePath="\Windows\HTC\Assets\Images\InternetPort al\youtube.qtc" />
<Link
Text="CNN"
NavigateUrl="http://tmobile.cnn.mlogic.mobi"
ImagePath="\Windows\_Bookmark_icon.qtc" />
<Link
Text="ESPN"
NavigateUrl="http://m.espn.go.com/wireless/index?z=TM"
ImagePath="\Windows\_Bookmark_icon.qtc" />
<Link
Text="Facebook"
NavigateUrl="http://m.facebook.com"
ImagePath="\Windows\_Bookmark_icon.qtc" />
</OperatorLinks>
</InternetPortal>
4)
Remove the line <BrowserExe>\Windows\iexplore.exe</BrowserExe>
This will now launch the lower left Bookmarks and lower right browser in Opera. (this is only possible, if you have already edit the registry in the previous tutorial)
Replacing the tag
<BrowserExe>\Window\iexplore.exe</BrowserExe> with <BrowserExe>\Windows\Opera9.exe</BrowserExe> only launches the "Earth" tab in Opera but the tabs will not be launched at all, not even in IE. Don't know why this happens.
You can even edit the Banner tag so that it doesn't go to the web2go website by modifying the NavigateUrl to "" or whatever you want.
5) Adding/Removing the Push Tabs.
Look for the tag <OperatorLinks>. you will notice that the three "permanent" tabs are located here. You need to remove the tag <Link> in order to remove them
For example: I don't want the facebook Tab on this screen.
So I remove the whole tag
<Link
Text="Facebook"
NavigateUrl="http://m.facebook.com"
ImagePath="\Windows\_Bookmark_icon.qtc" />
You can add more Tabs accordingly by following how the previous link tags are.
