Thanks! As long as our 1st gen Mini iPad, iOS6 is still considered current.
I am with AT&T, when I had a 4S... I only had the ability to use 4G.
Right you are, I just checked, only th AT&Te iPad Mini say LTE (if turned on), the 4s does not seem to have that option with AT&T.
If this is in reference to frequencies then are you are saying that the iPad Mini w/ LTE should be fine with the TMO sim?
And that older iPads or iPhones w/o LTE would only get slower (i.e. 2/3G) speeds with T Mobile?
