When will Apple's keynotes launched for iphone and ipod?

Apple has announced on last 27th September that on 4th October, 2011, they are going to talk about iPhone which is a clear indication of a new iPhone in coming. Online media is speculating that this new device will be called iPhone 5. As you may know, there is a huge amount of secrecy always clinging around an Apple product launch and this time is not a exception either. Apple is not going to let any information slip before the official launch and there are practically no completely reliable sources to get the information before the actual launch. We can have some speculative ideas about the official availability though, and according to most of the internet sources it will be somewhere around in late October or in November this year. There are also some speculations on the specifications of the new device and apparently Apple is going to have a brand new A5 dual core processor, most likely 1 GB or RAM and inside their new phone. It will also rumored to have a bigger IPS LCD screen of 4" size, a bigger battery and most importantly support for 4G networks on the the shoulders of LTE. The price and different models are yet to be known.
