On some custom rom large apps won't download from the android market!
This application runs a script to fix the issue, moving market cache to sdcard (internal for Samsung devices).
Tested on Samsung Galaxy i9003 and HTC Magic/Sapphire 32B!
ATTENTION! I'll not take any responsibility for any problems or damages you may encounter with using this fix: run it at your risk!
NOTE: when you connect to a computer to transfer file, market download will fail! Disconnect to install applications!
It will run the following commands:
rm -R /cache/download
ln -s /sdcard/market-download-cache /cache/download
chown -h system.cache /cache/download
