Hey. Cannot unlock Iphone 3gs 4.0.1 already jailbreaked....Help! I have jailbreaked with Limera1n. Then I installed Cydia and then I installed Ultrasnow and it is not working. Baseband: 05.13.04 It was working before on the same phone but before I had jailbreaked using jailbreakme and was using older version of Ultrasnow. Maybe some problem in new version of Ultrasnow? How to install previous version?
