If you want to put different themes on the viewty (like the i-phone theme) Heres what you need and how to do it. Please keep in mind that i did not create these themes and i learned how to put themes on a while back from another website. Also it is not my responsiblity if you do something wrong and you mess up your phone....

1)First down load "Theme manager" This has many different themes.... This is a .rar file so after downloading it you have to expand it.

2)Now down load EFS.. (Keep in mind that you might have to turn off your virus protection as this file is reconized as a virus but some anti virus but it isnt one so dont get scared) This is a .rar file so after downloading it you have to expand it.

3)Make sure your phone is in "Data Mode" and your using an LG usb cable not a best buy cheap one.

4)Open EFS then click on efs explorer then a new box opens check the box next to the phone name and click connect

5)Now using efs you must navigate to  LGAPP/Media/swf/theme

6)Delete theme_bg2.swf

7)Open up the theme manager folder named "Themes" on your computer. There you will see a list of themes. Open the folder you want and drag everything in it to efs (same place that you deleted theme_bg2.swf) In the theme phone you choose there should be a file named theme_bg2.swf.

8)Once it finishes loading into your phone disconnect the usb cable. The phone will not reset.

9)Make sure your not using any pictures as your homepage on your phone... If you are go into the phones menu and change your homescreen theme to the original black backround.

10)Now navigate on your phone to Go to menu
-Screen
-Handset theme
-Choose the second one which is called "Silver"

(If you were already using the silver theme on your phone from before them when your phone resets you will already see the loaded theme. Again remeber not to have a picture as your home screen wallpaper)

This is ALOT easier than it seems.
