刚从ebay买了一iphone 3G，上jailbreakme.com想unlock and jailbreak，提示说 the
version installed on the iphone is too new and need to be downgraded to
4.0.1/3.2.1 问了会破解的人，说 You cannot downgrade the baseband firmware
and
unlock, You will have to wait until a new exploit is out. ，想装 free apps，
需要 log in，问题是前owner设有password，现在这个iphoe完全不能用，咋办?
