So I have a 3GS on iOS 5.0.1. I checked my modem firmware and it looks like I can't jailbreak my phone, unless I'm out to lunch. I have 5.16.05. Can I downgrade this? Essentially I want to unlock my phone for when I go to the US. Roaming charges are insane and the addons from Telus are pretty much a rip off.
