If physical contact is causing a "short" or loss of performance, that's defective by design and needs to be addressed. If you're gonna skirt around the issue (not what I actually said but the stupid censorship here filtered it so I had to restate it) and make excuses for it, so be it, but as a consumer you - if you bought one - and all other purchasers should not allow this to just slide by and give Apple a pass.
Based on the reports so far, from multiple sources (this thread is a small source to be honest, several other forums have far more activity on this issue presently and far more actual reports of being able to replicate this issue easily), this is a manufacturing defect, period.
If the phone works in a lessened capacity just by holding it in the hand - something effectively essential to the use of a cellular telephone - then it's broken, and no amount of "magic" is going to brush that aside.
We'll hear something from Apple soon enough I'm sure. With today's official introduction/release of the iPhone 4, you can be quite certain this signal issue because of holding it isn't going to disappear. It's just going to snowball dramatically, and fast.
Engadget finally put up an article about it but, I swear it's so diluted and pansy I'd swear it was written with the intention of causing as little fuss as possible, almost to the point of it being not important enough to devote a posting to.
Weird, but that's what it is.
Engadget sure does put on a lot of lipstick for Apple...
I am NOT OK with having to use a bumper. I would be OK with a free bumper UNTIL they have a solution and actually FIX the phone. They have our addresses. Acknowledge the problem and send everyone a bumper. Doing this up front would restore some, I said some faith in Apple!
