With the iPad publicly available and the iPhone OS 4.0 out in the open, the only remaining item anticipated from Apple this year is the new revision of the iPhone hardware. Rumored to be called the iPhone HD, this new phone will now be the object of rumor and speculation until it goes public as well. As has been the case with past iPhone announcements, a new version of the software was revealed in the Spring and now a new version of the hardware should come out in the summer. Rumors surfacing today would seem to confirm Apple will hold to that schedule.

According to Apple and iPhone community site modmyi.com, Apple has reserved the same convention center they’ve used to announce previous iPhone versions for June 22nd. Although no official dates have been released yet for WWDC, this is within the usual timeframe of the Apple developer’s conference where the iPhone has been revealed in the past. If you get out your calendars you’ll also notice June 22nd is a Tuesday so that meshes with Apple’s modus operandi as well. While at this point we’re still doing a lot of reading of the tea leaves; the fact this date has been reserved, it falls within the usual dates of WWDC, and it’s on a Tuesday are fairly strong circumstantial evidence. I think it will be a pretty safe bet we’ll see a new iPhone on that day.

It should be very interesting to see what Apple does bring to the table in the new iPhone hardware. Much speculation has centered around what the new hardware will integrate. Judging from recent rumors of references to iChat in iPhone OS 4.0 the much desired forward facing camera is a lock. The new iPhone will also probably leverage the Apple-designed A4 system-on-a-chip currently powering the iPad. And of course, what will make this iPhone “HD”? With many of its competitors starting to make use of OLED and AMOLED screens, it is thought the new iPhone will get an upgrade in the display department.

Are you anticipating the new iPhone? Will the combination of upgraded hardware and software place the fourth generation iPhone back at the top of the smartphone market? Leave us your thoughts in the comments.
