How to save up for an iPhone 5?

I work in retail and i earn about 10.30 an hour because i'm fairly young. On average i work about 6 hours a week plus 3 hours on Sundays where i earn 17 an hour. I'm so bad with saving though and i always spend it on the first day! I get paid fortnightly. Sorry to be a hassle, but what are good ways of saving? And how long do you think it would take for me to save up enough! They are around $900.

Easy, stop spending it on things you don't need. Practice some self-control.

Look, just keep saving that money until the iPhone 6 comes cuz that'll be soon.

Save your money. You will get there quicker then you think.

Use credit and buy it on a plan - borrow to flash and call

Well I suggest that you save take like $60 a week and save it up and use the rest how ever you want. And a good thing to do is put that cash somewhere you won't be able to get easily or you can give it to your parents for save keeping and you won't be able to get access to it so you are limited to how much you spend and with a rough calculation you will be able to get one in 3-4 months time

If you can't control your spending then you have a long life ahead of you.
Get iphone 4 which is free with a 2 year contract.
