FYI: I have installed the new 4.0.1 software update. I'm in the UK. The signal loss issue STILL exists with the 'death grip' and i have proximity sensor issues when trying to make calls..the usual - ear outs calls into video calls, ear cuts off calls, ear mutes calls. Yadayada. (Before anyone jumps on my case I wasn't really expecting it to solve it given the info before the update was released). Also having problems trying to add details to an existing contact in that add to contact actually makes a new contact, making a new contact actually activates a facetime! Really fed up with Apple. Waiting for the press conference this morning (afternoon UK time)...depending on what answers they give the phones going back. Sick of Apple and their "we are invincible attitude". I've had too many of my Apple products go wrong in the last 18 months and too many of them been screwed up and had to go back or be replaced by new ones because of their inability to resolve things.
