If you adb into your phone, you can delete the spare parts apk and re-install ot from the market.
Code:
in dos:
cd [androidsdk/tools--wherever you hide that]
adb shell
mount -o,remount -t yaffs2 /dev/system/block/mtdblock3 /system
cd /system/app
ls
At this point, you find out what the spare parts apk is. I am at work at the moment and cant find out, but once you find it you will then....
Code:
rm [sparepartsfilename].apk
exit
exit
Then go to the market and search for "Spare parts"
