Can anyone please tell me how to remove the "MB" letters next to the memory number?

The reason why i want to remove it is because when i receive an email and im listening to the ipod, the status notifier wont display the email image. When i removed the memory display from sbsettings, i have all the notifications displayed. So i assumed its a space problem. That's why i thought about removing the MB.

Or if i could hide the clock on the status bar and use liveclock instead. I found noclock but im not using winterboard.
Is there anyway to hide the clock on the status bar without WB?

Thank you for your help
