There has been some speculation that the Apple iPhone 5 will be released in June to coincide with the Apple WWDC (World Wide Developers Conference), however there is a lot of evidence to suggest that this is not the case.
The first reason is that the iPhone 4S has only just been released on second tier carriers in the US so it would not make much sense if they immediately released the iPhone 5. If it were to be released so soon, then the smaller carriers would not see any return on their investment which is something Apple would not want.
The second reason is that there have been component manufacturers in Asia leeking information which pointed to a Autumn release date for those parts. This would would mean that the iPhone 5 would not be released so soon.
The final reason is that there is a lot of stock around at the moment of the iPhone 4S. Any annoucement of a new model would meant that it would be difficult to move that inventory.
So in the meantime, while we wait for the new device, lets just review iPhone 4S plans as their is some great deals on offer.
