Today is another day, so naturally, there are more iPhone 5 rumors going around. Another rumor has come from the supply chain, as they often do, indicating that the device may come with a larger display and a thinner design.

Previous rumors suggested that the device would be thinner and lighter, but this appears to be the latest rumor on the design of the device itself. AppleInsider’s Neil Hughes says Analyst Shaw Wu of Sterne Agee says his sources say the device will have a “slightly larger display than the current 3.5-inch screen found on the iPhone 4,” that it is expected to feature the “same dual-core A5 processor already found in the iPad 2,” and that it will feature a “similar form factor and size to the iPhone 4, but will sport a thinner bezel.”

MacRumors, which I would consider something of an authority on Apple rumors (if rumors can have authorities) says, “Wu does not have a terribly good track record when it comes to iPhone rumors, and some of the case designs floating around and said to have been designed based on the iPhone 5’s form factor instead show a slightly teardrop shape with rounded or tapered edges, with the latter feature much more akin to earlier iPhone models than the iPhone 4.”

Well, that’s why a rumor is a rumor. Who knows?

Eric Slivka at MacRumors also points to a BGR report citing a “reliable source” at Canada’s Telus talking about an interal document that has the iPhone 5 pegged for an October 1st release date – something MacRumors is also skeptical about, suggesting that this is probably just a placeholder date.

Rumors did arise this week, that the device is expected to launch in October, after months of rumors that it would come out in September (with August even being mentioned at one point). October 1 would put it right on the edge of September and October obviously, and as BGR points out, that would fall on a Saturday – the busiest day of the week for mobile stores.

Regardless of what the design ends up looking like and what day the device is actually launched. I think it’s safe to say that you can rest assured that it’s going to sell pretty well. Apple keeps managing to outdo itself in earnings reports. In its most recent, Apple reported a 142% increase in iPhone sales year-over-year, contributing to to $28.57 billion in revenue for the quarter – a record quarter for iPhone sales.

iOS 5, Apple’s upcoming operating system update will launch this fall, but no specific date has been given yet. Developers have now been treated to the iCloud web interface, however.
