Sorry this Truphone is not for the iPhone

Truphone has been living on my iPhone for a while but to admit I don't use it frequently. A I have a jailbroken iPhone, I use Siphon for all my VoIP needs.

However, recently, Truphone got an update enabling chatting and calling Skype users. This makes Truphone a really useful application.

Yesterday, I tried updating the application and once the process was complete, I ran the application and I got a weird screen saying "Sorry this product is not for the iPhone"

I guess something went wrong and the App Store installed an iPod version. I have not idea.
