I sent a Lypp alpha invite over to a friend of mine thinking he would have some fun testing our system before we released Lypp to private beta. What happened next was pretty damn cool.
On his iPhone he logged into his Gmail account and clicked on the invite link he got in his email. He was redirected to the Lypp alpha signup page and associated his Gtalk account via Meebo on his iPhone with Lypp. He then added the Lypp buddy to his buddy list and immediately upon doing so received a confirmation code. He pasted this confirmation code into the Lypp confirmation page and clicked the Finish button.
The Lypp signup was complete, all via iPhone and all within 3 minutes of getting the invite email.
He then called me and his business partner by simply sending the call command "call 6046297990, 650xxxxxxx" to his newly added Lypp buddy. His phone rang, "Lypp is completing your call". "Ring Ring", my phone started ringing. I was giddy, he and his partner were impressed.
So there ya have it, the first Lypp group call via iPhone, and it was free 🙂
