The only thing that will currently open a PDF for editing in ID is the PDF2ID plugin from Recosoft: http://www.recosoft.com/products/pdf2id
Keep in mind athat PDF is a final format, and you will not recover things like styles, anchored object settings or probably text threading, so even with the text in front of you you may have a lot of work still to do, and you might not be any further along than if you just save the text and export the images out of Acrobat.
http://markzware.com is actually coming out with a conversion plugin that works with InDesign. From what I have tested and seen, the conversion is quite accurate and fast.
If you are interested in doing a beta test, there is actually one going on right now:
Was very nice to test out this product and compare it to what is currently available in the market.
