Not saying my thinking is correct, but the lawsuit doesn't add up in my eyes as a reason for the holdup.
The business suing them is, or was, getting a % of the profits from downloads. This would be the only thing holding them up in regards to the lawsuit that I'm aware of, if that was what was holding them up at all. Cellairis and Truecare are selling the product which means there would potentially still be downloads. I cannot see that it would only be a % from downloads from the PhoneGuard site, it would be total downloads across the market. So I cant see that the lawsuit is the problem because it would stop all sales.
Apart from some goon running the website there is something else going on and I find it hard to believe that the PgoneGuard-MOTO logo means nothing. But then again, I'm finding it hard to believe anything at this stage.
