Be careful, this battery is erratic and occasionally just drops in juice without reason.  I've had mine for a year now and just last week I couldn't close my blackberry case and was wondering why. All the grooves in the case seemed to match..but then I noticed that my Seidio battery was slightly bloated and fatter.  I think it's gonna explode if I'm not careful.  I have put my OEM battery back in, despite the lower mAh and will try to get some replacement from Seidio, which I doubt.
