There currently is not a jailbreak for iOS 6. So, if you update now then you can't jailbreak it. If you keep 5.1.1 you can jailbreak it [http://blog.iphone-dev.org/post/24395681708/pre-dc|here]. If you jailbreak it you will not be able to update to 6.0. None of these thing will fix your no service problem.
