Regarding the dock connector, I think the description I gave of the problem, rules out any problem at the other connector.
I don't agree. Pushing the USB plug in only part way can leave one of the 4 pins "floating" rather than grounded. This can be misinterpreted at the other end as a signal. But using Sherlock Holmes observation, if you have eliminated everything else what remains must be the case. You have tried different cables, different USB adapters, (presumably) different ports on your computer, and check with your carrier and verified that tethering is provisioned on your account. All that's left is a problem with the phone, and, as you have other problems with the dock connector that makes it the most likely suspect. Have you tried inspecting and cleaning it?

I'm inspecting the connector with a watchmaker loupe; there are four contacts only. According to the schematics of the dock connector, they are # 16, 23, 25 and 27; respectively USB GND(-), USB 5 VDC(+), USB Data-, USB Data +. The same schematic also says
Pins 25 and 27 may be used in different manner. To force the iPod 5G to charge in any case, when 'USB Power 5 VDC (pin 23) is fed, 25 must be connected to 5V through a 10KOhm resistor, and 27 must be connected to the Ground (for example: pin 1) with a 10KOhm resistor.
The pins are all in correct position and shiny. For good measure I sprayed them with an electronic contact ckeaner, both on iPhone and connector side, with no change. But enough for this detour.
I know that the data pins work because I've been transferring photos to my PC without any problem. So the problem resides somehow with the interpretation of USB GND and USB 5 VDC, pins 16 and 23.
Dear Lawrence Finch,
Problem Solved!! The "charging is not supported
with this accessory" error was basically a 'cheap-o'
cable that wasn't authorized. I purchased an 'authorized'
USB / iPhone cable and the phone charges normally.
I even invested in a Otter Box Protective Gear with Holster/Belt
Clip for $45.00 on clearance rack at Wal-Mart. The 'real' solution
is simply making sure the charger and cable are indeed Authorized
Apple Supported Devices / Components. Knock-offs, and Cheap-o's
do not have the means to charge ANY device! It will cause Frustration
and Irritation! (As far as Net-10, I use the slower Motorola Phone
to send, both images and texts. If I can't send pics or video clips, I
store to the Motorola 2 gig Data Memory Card, upload to my PC to
facebook or youtube. It would seem, Net-10 'service' won't allow me
much freedom or tolerance sending any size videos, pictures or texts.
The slower Motorola flip-phone did allow me to send both photo and
text messaging MMS and SMS.) Thanks Again!

SOmeone needs to complie all this info on this thread; ultimately there are multiple go arounds but ultimately it's an apple software problem which encompasses not ony charging but low battery life, Wifi, and bluetooth problems.
I got rid of the 3GS and lost money, I bought 4 new in box units and they all behaved basically the same but not exactly I switched to older Samsung Galaxy S and I couldn't be happier.
I also noticed similar problems with my older iPod 4's due to the same software problems
Apple will not support the fixes on the 3GS' or the 4's, I think their motto is 'buy latest or else'... No more Apple for me, would like to support American but I need stuff I can rely on.
Hi, I posted earlier regarding this issue. I have an iPhone 3GS (actually, had three of them, sold two for 5c ugrades, I use the 3GS). The original Apple cable was too short for me to plug in the phone from the wall outlet charger and reach my desk, so I went online and bought a longer cheap cable for about $3.00. The cable never worked as a data cable, but it has for over two years worked just fine to charge my phone. The cable insulation is now cracking where the cables flex next to the end plugs, the printing has worn off the plug, but it continues to function fine to charge my phone. I'm just hoping you found your issue. Could be your cheap cable had a run of bad quality wire, too many ohms, or whatever. I've always noticed my phones charged faster and more completely (not kick out of charge early, say at 88%, which happened sometimes when using the Apple wall charger), when I charge them from a pure DC power source, and not a rectified AC charger. I don't know how clean the DC is coming out of Apple's charger, maybe you can find this on the net someplace, but that's been my experience. My phone charges beautifully from my Halo pocket power battery device, fast and right to 100%. My phone always also charges, with only an occasional rejection requiring a second try, from a cheapo $3.00 Asian-sourced cigarette lighter charger. That gets a pure DC feed, it just steps down the current. That's been working perfectly for over three years. There are also some good articles about charging circuits and how batteries build resistance to charging, which may be misread by the charging circuit, resulting in the rejection when plugged in. Good luck, I hope the Apple cable solves your issue.
I further tested my iPhone and cable with that of a travel companion. It would seem the error is caused by a combination of both hardware and software.
My iPhone is 3GS runing on 6.1.3, the comparison iPhone is 4S running on 7. My USB cable plugged in causes the error in my phone, but not the other phone. The other cable works fine with both phones. When my USB plug is pulled out by 1/16", it works fine with my phone too.
My cable used to work fine before I loaded release 6.1.3. My guess is:
- the software checks for a resistivity threshold of the cable;
- my cable is at the limit of such threshold, and partially pulling it out brings it back within the threshold;
- release 6 introduced a tighter threshold;
- version 7. relaxed the threshold, after many complaints.
I avoided Apple products for many years because I disliked their closed environment. With the release of the IPhone, IPad and Apple TV I decided to become an Apple user. Having just learned that I am forced to buy an offically licensed cable for my IPad, I am done. Why should I have to pay 10x the price for a cable so Apple can get more money out of me? My next phone will be android, no more Apple TV orders and my next tablet will not be Apple.
The company's creativity is dying, the products becoming stale and nothing new appears to be coming down the pipeline. You need to keep your customer base happy if you want to survive in a post Jobs world Apple.
Funny you should say that. I just sold my unlocked 3GS, and was ready to buy a 5S, so I had to wipe my 3GS to sell it. The SIM card still fit in my old Samsung T-209. So I charged the old cracked glass clunker that still worked and although it does not have the functionality of the 3GS, I already have all that on my desktop. What thrilled me is that after starting to use the old Samsung phone, its been three days of using and talking and the battery still shows a FULL CHARGE. I'm thrilled. No longer a charger cord noose around my neck, and staring at the battery percentage. I'm having really serious reservations about getting a new iPhone now, or any new smartphone for that matter. These old beat up Samsung phones are for sale for five bucks: who's going to steal it? Peace of mind at last. Out of the fast lane. Be seeing you. (P.S. - no charging problems either)!
We received this message on attempting to recharge our iPad: Charging is not supported with this accessory. Solution: the cord connecting iPad to plug was only intermittently carrying current (when I "toggled" that connector the battery-charging "bleep" sound was heard intermittently as contact was established or lost). We replaced the plug (probably not necessary) and the connector cord (absolutely necessary) and the problem ended. We believed, based on this experience, that the connector cord in question, almost four years old, had simply lost the ability to make a clean and definite connection. Problem solved, at least in this instance, for us.
I upgraded my iPad 1 to 5.0 and I got this message " charger is not supported". I tried the " battery doctor" app, it didn't work 2. Tried that whole turn of hold the key blah blah didn't work as well 3. Cleaning didn't work either. I knew my charger was an after the market charger so I gave it a possibility. So went to app store, since they already seen this problem the guy said its not the actual cable even it's after market, it's the actual charger that goes in the wall. He said " it doesn't supply enough juice" then he tried one from store to show what he means so $20 latter it works now. make sure you get the big charger with 10v not the small 5v one for phone ( even thought that's the one I used before and it was fine"
NimaVA, I'm not sure that what you wrote is factual. According to the schematics of authorized vendors the voltage of the USB connector is 5 V, and not 10 V.
My so called faulty charger and cord work correctly when charging an iPhone with a iOS version (7.0) higher than mine, but not mine (6.1). So I have to conclude that it is a software issue. One hypothesis that fits what my tests showed, would be that at one point Apple narrowed the parameters allowed by the sofftware to detect genuine vs counterfit chargers, only to have to back out at a later iOS release, after getting complaints that the threshold was too restrictive for some of its own production.
