They told people to turn off their WiFi because it interfered with the presentation everyone wanted to see...wow, arrogant indeed.
At the press conference, in case you missed it, Apple admitted the issue. Let's state that again: they admitted the issue. They also (apparently unreasonably) pointed out that other cell phones have the issue as well, and that 0.55%of iP4 owners---that's slightly over one-half a percent, not 55% which is apparently how the posters all over the web must understand it judging from the petulance---have experienced the issue enough to even complain about it. 99.45% did not complain about it. Yeah, the arrogance and dishonesty is rampant. Not at all like the whiners who are acting as if their left testicle has been removed.
If you have the issue, or even if you don't, Apple will fix it or give you all your money back. You will not be harmed in the making of a phone call to the 800 number.
In the real world, production schedules slip all the time; release dates are estimated dates subject to everything going according to plan. Sometimes production machinery breaks down, raw materials are delayed, work instructions/SOPs have to be revised and processes revalidated, the upscaling processes are problematic, etc. This is not "lying". Someday you'll get it.
"They do and say what they want not carring [sic] if it is true or not." What do you mean, exactly?
