I Love biteSMS but I really hate the Pink icon. Also, most themes available don't include the biteSMS icon. You can manually change the icon, but that's too much hassle particularly if you're like me who change themes often.
So here's a trick so that you can have biteSMS themed, by renaming it to the default Text.app (mobile SMS.app)
1. Download Rename.app from Cydia
2. Run Rename.app and rename biteSMS to
Text

After renaming, just hit the Home button and your Springboard will automatically reset. You're done!

So now, biteSMS will have the same icon as Text.app and will change with any theme you use (most, if not all themes include the Text icon).
I you don't want to get confused, you can also rename the default Text.app (mobile SMS.app) into something else. Or if you're like me who use the Categories.app, you can hide it in one of your category folders. You can also us Poof to just hide the icon away.
Enjoy.
