So today I ordered a replacement iPhone 4 with AppleCare using ARS. It will be arriving tomorrow! Fast! I'm wondering if I will be getting a refurb and if I should be worried about this? I've heard that refurbished units are "refurbished" with new parts, so it is essentially "new". And refurbs go through 2 different quality control layers. 1. Factory 2. Refurb inspection.
