Why theme is always incompatible in Sony Ericsson w20?

There are many reasons why the theme that you purchased or downloaded fail to work on your Sony Ericsson phone:

- the theme was incorrectly labelled as being compatible with your phone.

- the theme size does not match the screen size of your phone.

- the theme is in a file format not supported by your phone.

- the list continues...

To save yourself the grief of wasted purchases, try the following instead:

- make your own theme with the official Sony Ericsson theme editor. (Download it free of charge at Sony Ericsson website.)

- ensure that the theme you are about to purchase or download is in .thm format. Themes in .jar and .sis formats will not work at all.

- ask your family and friends who has the same phone as you what themes do they have.

- contend yourself with the pre-set themes that came with the phone.
