Ah, the shifting sands upon which the iPhone 5 rumour mill is built. No sooner do we all settle on the fact that it'll more than likely be a modestly upgraded iPhone 4 set to arrive in September, than everything changes.
Now, Apple's next iPhone has evolved again into a completely new entity, set to arrive not in September but a month sooner. Read on, if you dare.
This common wisdom-shattering allegation comes to us from BGR, which makes it worth repeating as the site generally doesn't deal in baseless speculation – even though this claim is delivered wrapped up in stock-standard phrases such as “independently confirmed” and “reliable source”, which usually see us reaching for a decent pinch of the nearest pile of salt.
Anyway, this reliable source reckons that talk of the iPhone 5 – or the iPhone 4S, as some are calling it – being simply an incremental upgrade on the current iPhone 4 are wide of the mark.
We're told to expect “a radical new case design” – though neither BGR nor its source seem able to clarify exactly what that means.
As for the release date, the source claims Apple is going to break with tradition and hold a special event specifically to launch the next iPhone in the beginning or middle of August, with the handset to go on sale at the end of the month.
That goes against existing speculation, which suggests Apple will announce the phone during its annual autumn event usually dedicated to the iPod.
Like we said earlier, we're only reporting the rumour based on BGR's track record with this type of thing, yet the same site has since reported on a Bloomberg piece claiming there's fresh evidence to support the original September launch theory after all.
Just another day in iPhone rumour-ville, it seems...
