Hey guys I have just read the recent dev-team announcement: "DO NOT USE LIMERA1N IF YOU USE THE ULTRASN0W CARRIER UNLOCK wait for PwnageTool to incorporate the limera1n exploit. This is so that you can avoid updating your baseband and losing the unlock (possibly forever)." I have used Limera1n and ultrasnow unlock to jailbreak + unlock the iphone before the announcement came out. What are the implications for this? What should I do? Is it still supposed to work if I dont upgrade my iphone? ps. I have iphone 4, 4.0.2.
