My dead iPhone 5

Ok, for some reason my phone never fails to give up on me before I could lay my hands on a new one. And this by far is the WORSE. So my bad luck with phone started years years years before. I've had my phone drop into water, phone dropped into water, soaked in it and then realise. And I've left my phone at bus-stops and lost it ever since. SO I'm in the pendulum of either losing my phone or damaging it. Or sometimes, have shitty phones to begin with.

So my first official 'atas'(high class) phone was the iPhone 4. I wanted to be extremely careful with it, being super gentle with it and stuff. Coming from a Sumsung touch screen phone, and I'm not talking about S series, I'm talking about the generation before that. To put it simply, touchscreen phones, but not smart phones. The Sumsung Preston if you remember.

So me being careless, I always used force to press the home button, until one day, it stopped working. But thankfully there's always the assistive touch and the unlock button on top. And being an idiot, I would always panic when the battery is at 50%, then would charge it till it's full. Then by the time I knew it, my phone's battery drained out faster than I could expect.

When I got the iPhone 5, I was super careful when it comes to the home button, like all I dared to do is to just gently tap it. And it still works fine, until the countless times I DROPPED IT. And one fateful day, it dropped in an angel when the first crash point was the lock button. And thanks to that, my lock button is spoiled. IT IS LIKE GOD FORBIDS ME TO HAVE BOTH FUNCTIONING AT THE SAME TIME. Kidding. But honestly, I think god is watching over my phone cause like looking at the number of times I've dropped it, is it wrong to call it the lord's miracles that it has NO screen scratches and NO cracked screen?!

But obviously, when you  keep on dropping it something is bound to happen. AND IT DID.

YOU SEE THAT BLACK HOLE OF ANNOYANCE. 

WTF is happening to my phone?! Now typing is becoming a problem. Also, look at the bottom of the screen, there is like lines on it. How can it survive till iPhone 6's release?! My plan is to buy a second hand BB Torch, since I wanted to have it for like FOREVER. And it'll hold for at least until I have a new phone when the contract finally ends. Thoughts?

UPDATE

As of recently, the hole got bigger and bigger, and the screen went crazy, switching between apps by itself. And after using the BB Torch for 6 days, I decided that using my old iPhone 4 was so much more convenient. There goes a wasted $130. Should I purposely drop my i5 to see if it will revert back?
