Apologize for 'tone'. I've 4s & been Sprint Business Client w/multiple lines 15+ yrs, so deal's excellent. Average technically, blogs & such confusing & overwhelming & can't ?*(%!^& deal w/cr@ppy @$$ signal any longer!!! Decided to go all Apple, done so slowly & just one PC device (notebook computer) left, but don't know WTF to do re: constant lack of cell signal. Please note, I'm 3rd generation resident of the Banana Republic (Miami, FL), where everyone can talk $#!+, but no one can do $#!+. Need viable solution & if can't implement myself w/ease, then whom, what &/or where do I turn? Thank you all in advance for your assistance.
