Looks like Sling Inc made an odd choice regarding which keyboard layout to use for the password field on the iPhone app. Quickest solution would be to enter a comma in the username field, and then cut and paste it into the password field. Hopefully the password field doesn't have any issues with the somewhat-unexpected character.
I have marked your answer as correct.
I never thought about that, but i just tired it and it worked.
I added a comma to the "username" field, and then copied it, and remove it, then pasted it in the password field and it did take it.
Yea, its strange that they would leave this stuff out.
Thanks for the heads up
