Hmm, interesting to hear. The XM6 seems like a neat little unit, but it's hard to commit to somehow. The slim design of the Glacier just seems so convenient. Choices, choices. Thanks for getting back to me about that. I also just finished making my way through the whole thread and you really seem to contribute a lot, so thanks for that too
As for the recently posted news of this not working with the GS4 International version, that's scary news. I've got a GS3 right now and soon I'll be moving to Asia, so I was looking at picking up GS4 once I touched down. I was looking forward to getting that Otca-core going and I was assuming that it would work with any of the USB DACs the S3 did, but I guess not?
Now it probably is also like you mentioned, Fuzzy, but it's also shipping with the newest OS updates on it, ones that most GS3s don't even have. So that worries me that it might end up being a hardware compatibility issue and not an update issue. And ha, the other problem of it being a software update issue is that unless you're buying the GS4 Google Edition from Google Play, you're not likely to see those updates roll out from your carrier within your lifetime :-P
Here's to hoping an answer is found soon though, because this single point is going to greatly affect which phone I buy in the next 2 months.
