How long would it take to save up for iPhone 4?

I really hate mine. The screen is cracked after my friend dropped it on the floor while drunk. The front camera doesn't work but this has been a problem ever since I bought the phone. We got it custom made to be pink so could this be why? Because we got the front and back of the phone replaced could this be why the front camera doesn't work? And how long would it take to save up for a new one?

It depends on how much money u make

From how much money?

"How long will it take to save up for a new iPhone 4?"
Nobody can answer that because nobody knows what your income rate is.

"Why is the front camera not working?"
It IS possible that wherever you got the cover replaced they may have sabotaged the camera in order to get you to go back and spend MORE MONEY on getting that fixed. Its always about money and people will do things to get it.

I recommend you buy a Samsung device, maybe an Galaxy S4 or S3 Mini.

It would be cheaper to fix it than to get a new one. My friend got her front screen fixed as her lock and vibrate button for £40. The iPhone 4 is around 400 so getting it fixed is much better. I have the iPhone 4 and mines in perfect condition, not a mark or scratch on it but mines on contract but I know I'd much rather pay to get it fixed than to pay for a new one!
