can't find a thread exactly on this, but when i got my iphone 3gs i had it on 3.1.2 and i jailbroke with blackra1n, it was tethered and i didn't like that but sometimes when i re-jailbroke it when i turned it of it just stayed on the picture of geohot or went back to restore mode, and then one time my phone started lagging and messing up real bad, and i mean real lag, the slider wouldn't slide and then it all went bad, so i ask how reliable is the spirit jailbreak?
