General :: App Downloaded But Didn't Install

I have downloaded a couple apps recently while in an area with a low signal. Not realizing that my phone was just waiting for the market to acknowledge the request I told it to download multiple times. As soon as I realized that it was downloading multiple copies I canceled all of them that I could, however, there was one that I could not cancel.

When I would check the market it would not say that I was downloading anything, but my notifications area showed that clearly I was. Once the download finished the app did not install. Now I'm stuck thinking that the data downloaded for the app is taking up space on my phone but I cannot find it to remove it.

I assume that the apk is just sitting somewhere taking up space but I cannot find it to remove it. I can download and install the app again, but that doesn't work the fact that this 8mb downloaded for the app the first time is sitting on my phone somewhere unused since the market did not acknowledge/track it.
