iPhone app update for iOS7

I'm reposting this project. My iPhone app was running well in iOS5 and 6. Beginning with iOS7, there is are a couple bugs. I need these bugs fixed. 1. The primary bug has to do with the way the app is computing a variable and then reading the database. 2. The secondary bugs are graphical, very minor. I need someone who is willing to study the code, find the OS7 glitch, and fix it. Time to completion - about 3 hours. This is a standalone app. I am looking for someone who is a very good communicator. If you are not willing to communicate with me frequently, if you are not reliable, please do not bid on this project. I am based in the New York time zone. That means you have to be available to communicate with me every day at a time we agree, between 9:00-22:00 New York time. If you cannot commit to that, please don't bid on this project. If I hire you and I cannot communicate with you, I will fire you and write a very negative review of you. If I like your work, I will invite you to a much bigger project, which will to create a fully revised web-based edition of the app. I do not hire based on price alone, I hire based on our communication. You have to convince me that you understand what I need and that you can do it. I have worked with freelancers for several years; I always pay on time. The only dispute I had was with a freelancer who did not do what he agreed to do, and it took him many months not to do it! If you're not interested in being a serious, zealous contractor, please don't bid on this project. If you don't have a portfolio, don't bid on this project. I'm willing to pay a little more to get a great result. Don't promise what you cannot deliver.
