My iPhone 4 will not charge, have used different chargers, cables, and docks, also a hard reboot is not working, what do I do now?

Question

Ok so I woke up this morning and found that my iPhone 4 was 2% and about to die even though I had left it on the charger over night. Also, you may want to know that the charging icon does appear over the battery, it just won't actually charge.  So I plugged it into my husbands charger which is an apple charger plugged into the wall. This had the same result. So we have some docking stations that simultaneously charge while they play your ipod, 3 different docking stations ended in the exact same result, a icon but no charge.
Next my husband did a hard reboot by holding down both the top button and the home button until the system turned off and rebooted. We tried charging after this will the exact same result. My phone has now died. Can someone please give me some idea of what to do next, just saying take it to the apple or AT&T store seems like the obvious answer, but are our options really so limited?
Also note that we have checked the bottom of the phone on the charging port and it is clean and to the eye unbroken.

Answer 1

yes, your option is as limited as getting it into the hands of an apple store employee (or if you have to ship it.. if there is not a store close by)
My wife's old 3G had this problem, it is a battery issue.  They replaced my wife's iphone within a day, but I'm not confident any amount of user troubleshooting will fix your problem
