I recently cracked my front screen of my iphone 4s....what is the best way to fix this if I have warranty?
If the screen is cracked then you no longer have a warranty since its voided if any damage. If you have insurance you can file a claim with a deductible. If not you can see how much it would be to get the screen repaired/replaced through apple I think or a cell phone repair shop but it will cost.
so if I have insurance, do you know how much the deductible would be?
You need to look at your policy or go to their web site.
