Some of the places to repair the front glass on an iPad front are Batteries Plus and iMaster Repair. Another option is to purchase a repair kit online through iFixit or eBay, and then fix it at home.
Batteries Plus is a nationwide chain with a long history of repairing electronics. To hire this service, use the store locator to find a local facility, and go in person to determine pricing. As of 2015, the facility is able to repair iPad 2, 3, 4, Air and Mini, but not the original iPad. No appointment is required, and the company provides a complimentary 6-month warranty on all repaired electronics.
Another repair option is iMaster Repair which specializes in repairing Apple products. This facility has pricing available on its website. For example, the cost of fixing an iPad Air 2 screen is about $300.00. Rather than going in person, iMaster Repair offers mail-in service.
At-home repair kits from iFixit provide the Front Panel Digitizer for the iPad 2 for about $40, with a one-year warranty. The website also sells tools such as screwdrivers, spudgers and opening tools. Another option is to purchase a cheap, used repair kit from a seller on eBay, with prices starting at about $15. These kits only have the 30-day buyer protection plan through eBay.
