To the majority it seems impossible, but a glitch with specific phone and broadband company's overlooks the system and yes, change is possible. But however it is forced to act as a barrier with no direct way through.
Too oversimplify what I just said?
Specific phone and broadband glitch - Yes, there's a chance you can get through.
iPod Touch 3G or 4G, iPad 1 or 2 - No, there's no possible ways to switch.
The barrier was adjusted to separate the mainly English speakers and those of other languages.
