Anyone else have the Straight Talk SGS2 and having issues with Amazon MP3 App? It won't log me in, then at some point it did log me in and when I try to download anything I get "Network error, try again when you have a network connection. Error 70" I have internet and it even plays the song samples. All apps work great, except for this one, which works fine on my Samsung Tab and my old Samsung Precedent. I get a similar error when I try to download my cloud music. I contacted Amazon about this, but I'm curious if it's a problem with all Straight Talk SGS2 phones. Anyone else got issues like this?
