Hi, I recently bought a iPhone 3GS and have just discovered a crack about 5mm long from the dock connector in the back cover, I was just wondering if anyone had this problem and how it was resolved.. I'm willing to buy a new back cover from apple if that is possible.. Does anyone know if it is possible?? I do NOT have phone insurance with o2, but I am insurared thru Barclays Additions in the UK. Thanks in advance.
