Interesting acquisition announced today....Blackberry to acquire Good Technologies. For those of you who don't know or are familiar with Good, it's basically a BYOD platform for enterprises. (Email, intranet, etc.) Not necessarily directly Sprint related, but many people use both.
I've seen some threads recently about the differences between SIM/UICCs and though posting a compatibility matrix would help people.
This is pretty straightforward. The matrix has every Sprint LTE device, and what UICC card is meant for that device. Mix and matching UICC card types probably will not work, but swapping around UICC cards for devices that use the same type of card should work properly.
Keep in mind, you cannot simply move your UICC card to another phone to use it. Sprint's device authentication system still requires the correct UICC and MEID to be on the account to authenticate properly and work.
Yes, I have been finding this 10Mhz channel at quite a few sites. Been there for a month or so at least. Last time I looked at it, the 3rd carrier was not aggregated with the first two. Not sure if that is still true.
