If you've cracked or broken your iPhone screen, you probably want to replace it as soon as possible.Smartfix offers a one-hour service for repairing screen breaks, and the cost of the repair is about $50. Most of these services also offer same-day service. You can get an inexpensive screen replacement on eBay, but keep in mind that you might have to wait a week for your phone to be repaired. You can also sell your iPhone and receive a new one, which is another option.
