Ever since I updated to 1.1.4, my iPhone charger (original dock plug) is doing the weirdest thing. When I plug it in, it goes back and forth between charging and not charging. If I have the sound on, it plays the "charger connected" sound over and over again, and if the sound is off, it keeps vibrating. The screen goes back and forth between the charging screen and the unlock screen. It does seem to be charging. It never did this before I updated to 1.1.4. Is anyone else having this problem? Do you think it's 1.1.4 or a coincidence that this happens now? It is *really* annoying. 
Edit: my iPhone is not unlocked, and it has no 3rd party apps or mods of any kind.
