iPhone 4's SYNC CORD PROBLEMS?

Take it back for replacement.

Simple.

It is a useable product....

You don't expect your tires to last forever, or your oil to change itself...

This is in no way indicative of an inferior product. As the other individual stated, take it to an Apple Store or call AppleCare at 18006947466

All types of cords are subjectable to fragility. The correct way to unplug your iPhone or iPod device is to grab the port, not the cord, and pull out gently. You can also buy a dock that fits the i4 and sync that way to avoid tugging on the cord.

The cord separation may be a design flaw, but it can be human error as well if you are improperly removing it from the iPhone. You can seek a replacement which may cost you some money though it should be covered under the one year warranty.

However you can use any iPod cord dated back in the early 2000 year as long as it's a USB to sync cable. Most of the cables are 5 volt USB which carried on from iPod Nano's second or third gen to today.

but thought I'd post here since Apple doesn't read those forums.

Apple doesn't read these forums either. If you want to make sure they are tracking problems, then call Apple Care (90 days free phone support with new iPhone), visit a Genius Bar, or send feedback:

They do read the forums, Why do you think they delete un-nessary threads?

Users with points can report problem threads to the moderators, and a moderator from Apple evaluates the flagged ones and can edit or delete them. But I'm pretty sure no one from Apple's technical divisions is reading these boards to see what problems are out there, or tracking anything to see what they need to fix. It is not a reliable way to bring problems to their attention.

If your two-month old cord is defective, then talk to someone at Apple who has the power to replace it (AppleCare or Genius Bar). You will not reach that person by posting here.
