[Chheda]

From past couple of days I am having Sony Ericsson txt (CK13) and I encountered with an interesting issue. as I am choosing wallpaper display into the landscape mode it did not getting adjusted at all. The wallpapers are getting shrunk. another thing, I looked into the settings and there was no way to create own playlists. Let me know if you are having any useful instruction.

I think the wallpaper issue is concerned with the firmware. What I am saying that you should look for any firmware update available. The issue could be resolved after upgrading the firmware of the phone.
You can create Playlist on your computer. Right now I am using Winamp to create the playlists but you also use Media Go.
If none of things were not useful to you than you should contact the service center and get further help.
