Change Icons in 6630 7610 6670 in the Theme
We know that we cant change icons in the 7610 6670 6630 .. In fact in 6600 we can choose a theme and we can choose a icone for another theme in the same 1rst theme .
But Now change icons just like 6600. its possible.
Although its abit complicated,

Step 1:
Go to themes and choose the theme of which the icons you want to use, press options>edited and change one of the setttings, for example, Change the theme to "ErikSakaiCute" first...

Step 2
Using a program like fexplorer, go to e\system\skins\theme_used_in_step1 and take the "xxxxxxxxxxxxxxxxx.ini" file

Step 3
Put it into c\system\skins\the_theme_which_you_wana_use. In my case the CheLin2 Theme
If there is any xxxxxxxxxxxxxxxxxx.ini file inside, delete it, then rename the new paste one "xxxxxxxxxxxxxxxxxxx.ini" file to the name of the folder

Step 4
You are done, exit the fexplorer and apply your theme..
