I recommend going through a paid service. I myself use iCrackr and it has worked well for me so far (having used it for four months straight now).
As for Spire on iOS 5.1.1, use Spite but get it from the official source ONLY! Otherwise if you try to get a cracked version of it your device will get stuck in a bootloop. Make sure to get Spire 3.0 the untethered one
