If you use WinterBoard I suggest you do what sidewinder suggests
ok, I recall i saw a very strange explanation on the BiteSMS support forums and apparantly "when the app is loading the images of background sms and springboard they intercept that request and took the image you want in path you want in the memory actually the background image is builtin in the app.. adding winterboard support means bring out of the app that image in an image file so winterboard and the app you like can change that image"
So I guess it's about hacking the binary then
i really dont wanna get winterboard just for this minor thing
searched for a thread like this but there was no real answer..
Can you theme the bitesms background on an IPHONE 4s [jailbroken] to black or something similar? Please answwer
You definitely can do it. I have it set on mine right now, but you have to be willing to use Winterboard and create a new theme.
If you create a folder and name it whatever you want, "BiteSMS Wallpaper," etc, then inside place a png that's titled "SMSBackground.png" just SSH that folder into the var/stash/Themes.xxxx folder and then activate the theme in Winterboard to make it work.
The png should be 480 x 375 to work properly, but only part of that png will be visible. For example:
This is the picture I'm using:
http://dl.dropbox.com/u/1101364/SMSBackground.png
and this is what it looks like in Bite:
http://dl.dropbox.com/u/1101364/bitesmsbackground.PNG
also make sure that you use png and NOT "PNG" as the file extension.
Additionally, changing the dimensions of the png's will not work.
this didnt work for me..
