IPhone :: App Downloaded Twice - How To Stop Downloading?

I've searched everywhere and can't find an answer to this; it's a slightly different problem than just waiting for it to finish and erasing it. I stated the TomTom download on my phone, it timed out, so I started and finished the download on the computer. Synced it to my phone. Now, since I opened App Store on my phone again, it started the download on my phone again and erased the completed copy that was on there. I've tried syncing with iTunes again to try and get the complete copy back on, but it won't do anything because the incomplete version is on the phone. I can see the incomplete download in itunes and I'm letting it complete on the computer, but it's going to take 17+ HOURS to finish (what the heck is wrong with Apple's servers? I know it's over a gig, but you'd think Apple of all places would have downloads running at more than 17kb/s on my 10mbps line). I've tried rebooting the device, no luck.
