apple stopped signing 5.0.1 a long while back, and tools like redsn0w only support downgrades on A5 devices ipad 2, iphone 4s
with saved shsh blobs. u have an A4 device therfor u cant depend on this method, backup ipod in itunes then restore your device to a stock 5.1.1 from apple and restore from backup. then rejailbreak using latest redsn0w version 09.12b2 and install necessary depository on cydia for apps etc. this will ensure you have the latest versions and not corrupt apps.
