I suggested her to go for some online services like ifixit, they repair broken iPhone 4 screen at a very low cost. Before that she had already contacted Apple, they were asking for a whopping $200 to repair her cracked iPhone 4 screen, So when she met Tom, the local vendor, and he quoted her just $70, she was so so relieved and happy. Today her brother has a repaired iPhone 4 screen, just the difference being. He has lost the warranty of his phone.
