Just wanted to post up some information, prior to all the phones starting to drop for all the providers, especially here in the US. One thing to keep in mind, that was noticeable with the Note 2, is that all the carriers made different tweaks to the software that had limitations.
The Quick Toggle Notification menu. All the providers had different items available than others. Some menu items were available on providers that weren't available on others (and vice versa).
So, if you get your Note 3 and wonder where a certain menu item is, it's likely the carrier (for whatever reason) decided to remove that item.
One of the quick toggles that Sprint removed was Blocking Mode (which, I really can't comprehend why). Widgetsoid became my savior for the items that were removed that I wanted as a quick toggle menu. I just created a notification widget that matched the same color scheme as Samsung's and I've been fine with my configuration ever since.
There were a few other items that were different across all the providers, but I really can't remember all of them. Just a little friendly pre-warning, before threads get started screaming and hollering at Samsung, when it's likely the provider that might have removed a software element that Samsung initially had in the international version.
Love the G-Note series!
