UIPopOverController for iPhone (currently only available for iPad)

Before I implement something similar for the iPhone, I'm wondering if anyone has implemented something similar of the UIPopOverController for the iPhone. This is so far only available for iPad.

See my implementation here: https://github.com/werner77/WEPopover

It has the same interface as the UIPopoverController but is generalized for iPhone and with support for custom background views.

I have provided another alternative SGPopoverController at http://github.com/KJoyner/SeaGlass. Like the WEPopover, this has a similar interface to UIPovoerController but works on the iPhone. This version handles more corner cases, works both modally and non-modally, supports passthrough views, and more.
