"I don't get it. It says public beta now. Says it will send a link to install by sms link or by download to PC and then the email comes telling me that I will get an SMS, which I cannot use since i only use wifi and not a data plan. There is no instruction or link for PC download. I download and install the cab from this thread and now I have to enter a username and password. I submitted my email, but there has been no password stage thus far. Where do i get a username and password."
all you need to to do is open up
www.skyfire.com in your mobile browser and sign up. it will recognize your phone (even on wifi.) enter your cell number. check your text messages. you will be sent a download link. go back to your ppc and manually enter the url that was sent to you via the text message.
you will also be sent a confirmation registration message via email.
it worked for me and i don't have a data plan on my ppc either. just wifi.
