Floating mail icon in status bar
So I received the iPad yesterday and, obviously, the first thing I did was jailbreak it. After setting it up and visiting Cydia to download some apps, I noticed that my mail icon randomly appears next to the battery percentage. It may sometimes go away if I launch an app (I've noticed this with native apps), but that's not always a given.
I thought it was a theme (which may or may not have been compatible with the iPad), but I've since uninstalled it. The problem still pops up (no pun intended). After a hard reset, it still appeared as well.
The iPad is not even a day old, so if I have to, I'll just restore and set it up as new, but I'd rather hold off on that until further notice.
Has anyone come across this? I know I can just backtrack and uninstall each jailbreak app I installed, but I figured I'd ask just in case someone has seen this and knows what caused it.
I do have infinidock, but I uninstalled it. The problem still persists.
