its the 5.0 os.. it doesn't work with the new OS yet...
I will preface this by saying I don't have the Storm 2, however, Shazam works fine in a Storm 1 with 328 OS. Shazam would not complete setup on some of the earlier leaked 5.0 OS versions, but works on both 323 and 328. I assumed that it would work on 320 as well. Anyone out there who has made this work?
