Not really. There are so many tweaks for the statusbar.
There are a few ways to manipulate the status bar to change the icons and info. Sbsettings, allows you to add date, memory usage and a couple other bits of info. You can change the 3G, wifi, battery and signal strength symbols with individual downloads, or you can download status bar tweaks like "statusbaricons (ios5)".
And then there are themes that change the whole look of the ui, including the status bar. I'm currently using the Silex HD theme, which is ios5 friendly, but have altered the code a bit to make it my own.
In the past that I've used it, it affected certain aspects of my phone that I didn't want it to touch with just the default settings on. And from my experience, it's also had a negative effect on the battery life of my phone too.
