I know that the 4s has the new A5 dual core chip but, does it really run on both cores? I over heard a guy at the mall trying to talk a guy into an HTC galaxy s2 or rezound over the iPhone 4s stating that the before mentioned HTC phones are the only ones on the market truly running on a dual core processor :rolleyes:
 
Yes, it runs both cores ... that guy didn't know what he was talking about ... Samsung, Motorola, etc. have dual-core phones.

That guy doesn't know what he's talking about. Why would Apple or any company invest money in a dual core chip and not write their software to make use of it.

Further I doubt he could cite any sources or evidence of his claim.

An HTC galaxy s2 you say. He must be a great salesman
 
Not sure this is a legit thread..... this is the guys first post on this forum and it's THIS post? Bogus. Looks like someone trying to start up another us v them thread.

To OP, why have dual core chip if it doesn't utilize both cores? Common sense isn't so common I guess.
 
Of course it's utilizing both cores, what sort of question is that honestly.

You can tell just by using it compared to a 4. It's not a million times faster, but it's definitely snappier.
 
/begin car analogy

It's like having buying a car with X cylinders but no fuel gets injected into half of them.

/end car analogy

I realise there are cars that do turn off cylinders to 'save fuel', but lets keep this simple, k?

AFAIK iPhone/iPod Touch/iPad has had the theoretical support for multicore CPUs since iOS4. The key word is "Grand Central Dispatch"

Here's Apple's introduction:

In order to take advantage of multiple cores, a computer needs software that can do multiple things simultaneously.
...
there needs to be a way for applications to take advantage of a variable number of computer cores. The amount of work performed by a single application also needs to be able to scale dynamically to accommodate changing system conditions. And the solution has to be simple enough so as to not increase the amount of work needed to take advantage of those cores. The good news is that Apple’s operating systems provide the solution to all of these problems,

He said it because it's easier to sell an iPhone. Infact at this point in time they pretty much sell themselves. People associate quality with apple. They believe they will get a better experience. Holding an iPhone backs that up. I'd go as far to say that salesman spends most of his time trying to talk people out of an iPhone onto other products because he gets more commission on the others.

I believe it's totally legit. I've heard dumber things come out of salespeople's mouths. Sometimes they believe it because it's what their salesmen colleagues have told them. Other times they're outright lying to steer you towards another purchase. They'll even change their stories from day to day. It all depends on what the store is trying to move that particular day, and where the highest commissions for sales targets are.

^^ This. Or, it may be a wireless reseller that doesn't sell iPhones.
 
The salesman also told me that the iphone 4s only uses 5MP camera

Because he's a salesman, so when his lips are moving he's lying.

This.

I'm just polite but firm. I say that I know what I want, and if I want any kind of extended warranty or insurance I'll ask for it before they even get a chance to try and sell it.

When I bought a 43" tv from comet I carried it out to my car myself because I know they usually try to sell you stuff when they're wheeling it out to the car. :D

In comet when they tried selling me insurance for a dyson I told him when he kept pushing "look if it breaks I'll just chuck it down the stairs and claim on the house insurance" You should have seen his face. Only time I've seen them lost for words.

Yes i was kidding. Was only way to get him off my back and just finish the sale.
