I was thinking about buying a new iPhone 4 from the Apple store, but I use T-mobile and would want to jailbreak\unlock it. I'm assuming any phone I buy now would be on the new firmware, so does that mean I can't jailbreak it? From what I understand, a way to jailbreak it is on the way, but it may never be unlockable. If anyone could clear this up for me, I'd appreciate it.
