there is a full version. i contacted the author. this is what he said
1. there is a full version
2. there is a trial version
if you pay him via paypal and give him your IMEI number, he will make #2 last forever - no limited trial. for #1, he has submitted it to nokia store and waiting for it to be published.
i also asked him if i can get #1 first without waiting for nokia. he said it's possible by paying him via paypal but he did say that he is afraid i might give it to someone else. fair enough. so i guess we wait for nokia store version then.
