I've been repairing iPhones and iPads since 2009, both as an employee of Apple, Inc. and as an independent contractor for the most demanding clientele in North Scottsdale. Over the past 5 years, my business has greatly expanded to include small business IT and social media consulting, making it harder for me to justify the time and opportunity cost of repairing iPhones and iPads.
These days, I proudly refer my clients (including celebrities and prominent members of society) to Art and Kristian at Best AZ iPhone iPad Repair. They're centrally located, and they do the job better, faster, and less expensively than I could.
The only thing they don't do is mobile service -- but I've been trying to convince Kristian to take on that role.
Take it from this literal former Apple Genius: these guys get the job done right the first time, quickly, and for less than you'd expect.
