Dear Beta User,
This email is in response to your inquiry about when you will receive
your invitation to download Skyfire We apologize for the long wait.
When you get the invitation to download the beta depends when you signed
up. Please look at your beta confirmation email, and if it's dated
between January 28 - March 1, you are in the Beta 1 program, and your
invitation to download is coming. If it's dated after March 1, you are in
Beta 2 which will launch this summer.
We know that we said we would fulfill all of Beta 1 by the end of
April, however, it’s going to take us a bit longer to get to everyone. We
have been hard at work on Skyfire 0.6 as well as moving to our new
data center and building out our infrastructure. Now, we can put a more
finished released, Skyfire 0.6, into the larger beta community and we
can accelerate the pace of our invitations to download to the Beta 1
community.
We are anxious to get Skyfire 0.6 on your phone. When that happens, we
look forward to hearing what you think. Your feedback will help us
create an even better Skyfire 1.0.
Thank you for your patience and understanding; we truly believe we are
worth the wait that is almost over!
Thanks,
Skyfire Support
