May 27, 2015 6:28 AMby Rudegar,no ios device ever supported downgrade since the first iphone 1 was released in 2007
likely reason is that keeping support for many versions at once is very very very expensive
every bug found in the latests ios version would have to be verified if it's present and how to fix it in all older
versions
