OzStock sometimes have appealing deals.
Unfortunately, the rep has never explained why they offer lesser warranty terms for some of their goods. If goods are second-hand, factory-seconds, grey imports, or otherwise subject to questions of quality, then this should be clearly presented.
For this reason, I've decided not to buy from them until they are more transparent.
Whats the dif between 4pin n 6pin?
I don't get this either. Looking at the linked picture of the plug showing the pins, it seems the 6 pin version has pins 1,15,16,23,25,27 connected, whereas the 4 pin version only has 16,23,25,27. The addition of pins 1 and 15 seem to be additional ground connections and are electrically connected to pin 16 anyway. They don't seem to provide any additional function at all. According to http://pinouts.ru/CellularPhones-A-N/iPhone_connector_pinout… here are the functions of the relevant pins:
1 GND Ground (-), internally connected with Pin 2 on iPhone motherboard
15 GND Ground (-), internally connected with pin 16 on iPhone motherboard
16 GND USB GND (-), internally connected with pin 15 on iPhone motherboard
23 5 VDC (+) USB Power 5 VDC (+)
25 Data (-) USB Data (-)
27 Data (+) USB Data (+)
Pins 25 and 27 may be used in different manner.To charge an iPhone 3G / iPod Touch 2nd gen or Ipod Classic (6th Gen), usb data- (25) should be at 2.8v, usb data+(27) should be at 2.0v. This can be done with a few simple resistors: 33k to +5v (23) and 22k to gnd(16) to obtain 2v and 33k to +5v and 47k to gnd to obtain 2.8v. This is a notification to the iphone that it is connected to the external charger and may drain amps from the usb.
It's also possible to charge the iPod's or iPhone's battery to make use the of internal +3.3v output (18) terminal to connect the USB Data + (27) thru a 47k ohms resistor and the USB Data- (25) thru a 47k resistor to the USB Power source +5v (23). This way the USB function is still useable for normal operations and makes it easier the fit in a plug. The resistors are not to critical 2x 150k's still work.
Will these charge iPad from USB source?
I've purchased two cheap $2ish ipad cables lately from a guy on ebay and also deal extreme that supposedly can charge and sync.

What I found is that my iPad v1 does not support the cable for charging no matter whether plugged in to USB, or to the Power adapter. If I plug my legitimate cable in, all works perfectly.
The iPad can be detected when using the cable via USB from iTunes - but updates are problematic.
I'm waiting on the ebay seller and deal extreme to send me a replacement!
I bet they don't work either.
Maybe I just got unlucky.
Chucked out a cheapie from a previous deal. Stopped charging after a while. Will try to avoid no name iPod sync and charge cables.
OzStock ship from Australia, though. I don't know what Hong Kong Post is like at the moment but they're probably already starting to slow down in the lead up to Christmas.
Edit: "Dispatch in 5-6 working days"… lousy.
Only one meter in length, sufficient for syncing but Pain in the ass, when ac charging
