What should I do if I crack my iPhone?

If you have dropped your iPhone and smashed the screen. The following are options you may consider for replacing it yourself: 

1. If you have AppleCare, you may be able to get it fixed or get a replacement through Apple. 
2. Another option is to take it to a company that fix cracked screens. The problem with this approach, however, is you have no control over what your original screen is replaced with, or how well the repair is carried out. Both replacement screens and workmanship are variable. If you know someone who has had an iPhone screen replaced and they're happy with it, go for that. If not, do some research before you hand over your iPhone.
3. You could, of course, replace the screen yourself. All you need is a replacement front panel, LCD, and a lot of luck . Keep in mind that this sort of DIY job will void your warranty and it's unlikely to result in a pristine iPhone. On top of that, the quality and cost of the replacement of a front panel/LCD varies enormously. 
4. A preferred option for repairing is to take the iPhone to one of our two stores and book an appointment. Given the cost and unpredictability of repairing the screen yourself, we will fix it at a reasonable price.
5. Another option, particularly if the screen is cracked rather than totally smashed, is to do nothing. If you can still use the iPhone, there's no real reason, other than cosmetic, to repair or replace it (use a screen protector to save your thumbs from getting nicked). 
6. Finally, get protection. If your case doesn't have protection for the screen, buy a separate screen protector and use it. That way, the next time you drop your iPhone, the result might not be so catastrophic.
