It works on other JB 4.2.2 and yet, on my (and wife's) G2 it says 'Internet connection not available' when you try to connect.
Now, I've promised not to root my device for a year, so, this is where I'm stuck.
I've emailed the developer, but, it seems like they get it done elsewhere, because they say it's been tested to work on 4.2.2
Any help would GREATLY be appreciated.. PM me, and I'll give you a login account to see if you can get it to connect.
Here's a link to the app in question.
