I have an Iphone 3gs with iOs 4.2.1 BB 5.15.04, successfully jailbroken but can't be unlocked, right? I have been waiting for the unlock but its taking a bit too long now...

Does anyone have an idea when the update will be released?

Im planning to upgrade my BB to 6.15 so i can unlock it, but before i do sumthing stupid, can someone give me some pros and cons of this BB? I really need to unlock my phone right now...
