You can’t charge the iPhone 3G on iPod Audio Systems

Black and red -> 5V

Green and red : 3V

On my PC : charging
PC -> USB hub -> Iphone : charging
Just the USB hub -> NOT charging ⚠

My conclusion : the data line has to be active before the phone acceps 5V

In theory .. if I put a resistor between the data cable and +5V so that it gets around 3V it should work ...

What do you guys think ?

I agree that you're on the right track. I have a cigarette lighter USB power adapter that works with my iPhone 3G. I opened it up and discovered that it has the D+ and D- pins (green and white) shorted together with a 75 KOhm resistor connected between the data lines and V+ (red) and a 51 KOhm resistor connected between the data lines and ground (black), which results in 2V being applied on the data lines relative to ground, just like you measured.

Really? Alot of people say it does not work with the hi-fi and I really don't want to have to get rid of mine!

I want to go on record as another customer who is astonished at Apple's harsh and indefensible decision to essentially negate the accessory investments of tens of thousands of their customers by changing the power configuration of the dock connector. This is a change that could have been publicized, and gradually phased in as vendors were able to accommodate it. I sincerely hope this is a misstep that can be fixed with a software update. I realize it was an intentional thing, and not an error, but that makes it worse really. It’s a bad business decision, and should be addressed. I am new to the Iphone, and I love it, but I am greatly concerned at the handwriting on the wall.

I went out an spent $100.00 on a brand new USA-SPEC IPod interface (Which was advritised to “Work with the new Iphone) for my new Acura, spent another $85.00 to have it installed, just to find out Apple changed the "standard" way the dock connecter is used. Did anyone else consider the dock port to be more or less standard? That' a design Bennie I gave a lot of merit to Apple for. My mistake.. Fortunately for me, I will have the privilege of paying USA-SPEC another $20.00 in 6 - 8 weeks for an updated cable that will solve the problem, (I am no happier with USA-SPEC than I am with Apple really)
If I had a factory interface, I'd be completely screwed, like many others here are. I'd be REALLY, REALLY mad at Apple. I encourage all of you out there who have been essentially cut off of your investments in IPod-ware to speak loudly and clearly to Apple, Corp that you are (to quote an old move that shows my age) "Mad as ****, and aren't going to take it anymore!" We have a duty as consumers to let the big corporations know that this is just not OK, and we will not stand for it. I am seriously considering returning my Iphone while I still can.. All of this and no search capability to find an e-mail I need?...***?

Folks, it appears an adapter may soon be on the way.

Ridax offering iPhone 3G Charge Converter

Ridax, a company that sells various iPod Dock Connector accessories, has begun taking pre-orders for its iPhone 3G Charge Converter. The small accessory, the design of which is still being finished, will allow iPhone 3G owners to use older iPod and iPhone charging accessories that are currently incompatible with the 3G to charge the device by converting the power stream to suit the iPhone 3G. It will feature both male and female connectors, as well as a mini USB connector on the side to provide a way to charge the device when connected to a non-charging, Dock Connector-equipped accessory, and will also function as a short Dock extender. Ridax’s iPhone 3G Charge Converter will be available in September for $40; those who want the device sooner can pre-order a $45 “bare” version which will ship in August, followed by the plastic cover which will arrive in September. There is no guarantee that the converter will be safe to use with all accessories, so use caution in ordering.

Hi I have an Ice PW100 from Dension but it does not charge...

What type of Ice do you have?

I just received the Kensington Car Charger Deluxe (Model #: 33433) [http://us.kensington.com/html/14486.html] for my iPhone 3G from Amazon.com and it charges it beautifully. The charger docks in my cigarette lighter securely and plays via the aux-in on my headunit. I've actually missed using the iPod controls on the iPhone 3G instead of controlling it via my headunit. Now I’m able to use the Maps app and GPS with ease. Plus the charger allows me securely hold the iPhone 3G with the Belkin Silicone Sleeve!

Noxien,

Firewire is an excellent technology from external hard drives, as well as professional audio and video work. Especially when working with uncompressed content.

A lot of professional HD cameras use Firewire 800 for example.

However, iPods have not supported Firewire syncing for a few years now.

Hope this helps,

Specifically, since the third generation iPod.

If I use the Kensington 4-in-1 solution, which would let me charge and also control the iPhone iPod through my Scion's audio unit, what happens if I get an incoming call? Can I swithch to phone mode without disconecting, or will the phone be unavailable?

Which one actually works?

I want one of these but dont trust the shops (or the boxes...)

Anyone got one that actually functions?

Ok not trying to be a troll here but, even with all these suggested solutions i honestly think the issue of us having to spend more money to resolve an issue that should never have been encountered to begin with!

-What's the point of having a product that is iphone ready or certified when in actuallity its not? Again having the iphone ready label is an official gurantee that states that the product is compatible with both current and upcoming hardware (cited from ilounge.com) So what good is this guarantee at all given the current circumstances that people are facing? To me that constitutes as false advertising/misrepresentation.

-Apple did not communicate these changes to the public or the companies who manufacture accessories. So imagine the dismay of someone who bought some accessory that was supposed to be iphone ready a few months, weeks or even a day prior to the release of the 3g. Had Apple choose to be communicate this, people would have been forwarned and items that were not iphone 3g ready would have been recalled, replaced with ones that were prior to the 3g's release or customers would have been better prepared along with companies who deal with apple.

*(If anyone from Apple actually reads)*
I sincerly would like and appreciate it if Apple would post an official statement notifying the public either:

A) "yes we are releasing adaptors"
B) "We will have a patch to resolve this issue when 2.1 is released"
C) "Sorry but you folks are s**t out of luck and will have to find a solution on your own.*

*I honeslty think it would peeve people off more spending all this money to buy 3rd party adaptors or chargers and then find out later that they didnt have to cause a patch was already planned or that apple had thier own adaptor that they were going to release in the store.*


Seriously id appreciate an official statment than playing this guessing game of what apple intends to do.

Actually my personal understanding is the "Works with iPhone" documentation provided to accessory manufacturers says USB charging. There was indications of the change as early as mid-2005 for accessory manufacturers, when Firewire syncing support was dropped from all iPods. The original iPhone was released in June, 2007 and never supported Firewire syncing.

It is simpler and easier to design a car adapter that charges via the Firewire pins since the power from the car is already 12v. The USB pins require the voltage be 5v.

Hope this helps,

Well considering that not all consumers are aware of of these changes and that it was more within a small community circle.(even some manufactures like SCION was never made aware of this fact),and since there is no posted label on the actual iphone packaging or website stating that the Iphone 3g does not have firewire support should not fall on the shoulder of the consumer.

In all honestly i find your statement vague that firewire support was never supported for the 1st generation iphone since both the 1st generation phone and the itouch worked with the built in proprietary cable that came with my "2008" scion.

I simply just want a clear statement directly from Apple with thier plans regarding this issue. Its really annoying trying to contact thier technical support group via email and not recieving any type of response and the people at the Apple store or phone support have no clue whatsoever.

blkmagik,

If the manufacturer participates in "Made for iPod" or the "Works with iPhone" programs, they would be made aware of it. However, a lot of device manufacturers do make devices without participating in those programs, and the access to technical information and diagrams that it includes.

In addition this article, originally published in 2005 has that information as well:
