One of the lander's feet is visible in this CIVA image from the (final) landing site on 67P/C-G.
So the good news is that the Philae lander is at rest on a comet. The bad news is that we still don't know exactly where on the comet.
Philae arrived at almost exactly its planned landing site -- site J -- and bounced. It bounced to about 1km off the comet, spinning slowly. For about 2 hours it was in space and then it hit the comet again, and bounced again, but this time for only a few minutes before it came to rest where it is now... wherever that is. Wherever it is now, it is not getting as much light as it would have gotten at site J. Since Philae is solar powered, this is not good.
However, the batteries have charge for more than 60 hours of operation, and the instruments on the lander are working and returning data. CIVA has returned its first panorama images, which required a lot of processing because the light levels are low.

All the science instruments on the lander are live, and many of them have already returned data. However, some of the experiments require mechanical motions -- the drill, for example -- and given the precarious orientation of the lander and the risk of pushing it off the surface again, these are not being activated as yet. The chemistry experiment COSAC, which depends on samples of the surface material of the comet, is thus on hold, at least until data from the less risky instruments has been acquired. Since COSAC is central to the Rosetta mission, ESA still wants to acquire samples, but not on the original First Science Sequence schedule.
But the clock is ticking because Philae's batteries have a finite life and the solar panels are getting much less light than planned. ESA scientists are considering possible ways of changing the orientation of the lander (using the landing gear, which is active) to improve stability or optimize exposure to sunlight.
So the situation is far from nominal, but a lot of good physical science data is being acquired. The chemical data astrobiologists want is still tantalizingly out of reach at this time.
