Since upgrading to an iPhone 4 from my trusty 3GS, I have had poor reception and many lost calls. Optus said to take the phone into to Apple - Apple say it has only dropped 3 calls in the last month (not my experience) and so refer me back to Optus, so I thought I should log the call issues here:

Today whilst driving home, I had 2 calls dropped - I had to call them back - one of them twice and on the third time we gave up. I also hung up on 2 other calls, initiated by me, because there were so many words in the conversation dropped that we could not sustain the conversation.

All in all, I had one reasonable call, and 4 dysfunctional calls in a 45 minute period. NOT a good communication story
