I've been having similar issues, but with my laptop instead of my phone. I've been able to install previous versions but all of a sudden I can't download this one. It'll bounce between "Network Error"" and "Forbidden".
Update: I just re-uploaded Beta 1.3.5 and it's packed differently. If you can, give that download a try and let me know if that's helped get rid of the 'forbidden' issue!
