Mine's a week 42. It shipped from Apple on Oct. 18 which is the first day of week 42. It said "prepared for shipment" on Friday the 15th which is week 41. 😕
So far everything is working swimmingly on my phone. MMS seems to have some issues but I believe it's related to my carrier so I have to call them about it. I have some weird signal issues in my house where the signal bars seem to jump around a lot, from 5 to 1, 1 to 5, etc. but it doesn't appear to be related to covering the black line on the left side (or the right side or the top) or where I hold it at all. I can't compare to my old phone since prior to this I was on CDMA and with the iPhone I'm on a new HSPA network. At work, I'm at 5 bars sitting at my desk and it doesn't matter how or where I hold it, it stays at 5 bars.
