Did Apple really know about the antenna problem before release?

A few months ago Apple decided to take screen protectors out of their stores. Apple said that all of their products are built so they do not need cases or any other type of protection, which leads to this question: Why did Apple sell cases when they released the iPhone 4? Is it because they knew that the iPphone had antenna problems? Is it because they wanted people to make their iPhones look different?

What do you think? Obviously Apple knew about the problem. Tthey are just saying they already knew in other words.

Apple Must if know of the antenna problem. I watched the press conference on June 16. When they check the the signal of the cell phone they are in a large nearly empty rooms with nothing that could interrupt and/or interfere with the signal. Even the equipment to test it are remote room. The only things in that room are shields to prevent other signals from coming in, the iPhone 4 and the person the test the phone. Thats it. I'm thinking that apple only tested it in the building.I don't think they took this phone on a proper test drive outside the building. Steve jobs even said that every smartphone will have these problem. In Steve's words " This problem is not unique to iPhone 4". They even tested it their building. People have been overreacting thinking that the the signal has been falling four to two bars then its just falling four to three bars.Bottom Line Every smart phone has problems.
