I mean in all seriousness...
And not to sound rude, as you say the apple tech was to you...
But if you're out of Warrenty, and the phone is not apples responsibility after the Warrenty, than why would they just give you a new phone...or better yet even attempt to repair it for free?
This is why more and more people are turning to either getting a new phone every year or every other year, mostly because you are under apple or the carriers umbrella.
If my car, my watch, my tv...basically anything...stops working and it's out of Warrenty, I'm screwed and on the hook for whatever repair, or replacement. Whether it's my fault, or the moon, sun and the stars...it's all the same to whoever you're complaining to when out of Warrenty.
My advice, do one of the many upgrade programs that either apple or the carriers have available, it takes the headache out of situations like this.
Good luck.
