I have the original iPhone and am on the waiting list to get a new iPhone4. After reading all these signal issues depending on how you hold it, I decided to test my original iPhone. I removed my silicone case. I first held it as I normally would - phone in my left hand covering the lower 40% of the back of the phone. This happens to be the black plastic area where I believe the antenna is behind. Using SpeedTest, I had download speeds averaging 25kbs. I had 3-4 bars. I then rotated the phone 180 degrees so it was upside down. I held onto as little of the phone as possible (the top part of the phone which was now on the bottom). Using SpeedTest, I had download speeds averaging 100kbs. I still had 3-4 bars. I ran the above 2 methods 4 times each -- results fluctuated slightly (about 10-15%), but were very close. This is a 75% data download drop when I hold the phone "normally". I suppose people will say this was an unacceptable design flaw. I say, I have loved my iPhone the past 3 years and it has been the best phone I ever had. I wish I had realized this earlier as I would have adjusted how I held the phone at times. My point is... it appears there has always been significant drop in data speed depending on how you hold any iPhone. As for the data totally stopping when touching the gap (I have seen in some videos / posts), I will always use a silicone skin with the new iPhone4 so it won't affect me. For those that don't want to cover their phone, I understand this may be an unacceptable design flaw & I understand your frustration with Apple. If that is the case, you will need to decide if you can avoid touching the phone in that area or if you need to return the phone and wait until it is fixed. If enough phones are returned, I'm sure a manufacturing change will be made (probably a design "tweak" being done right now). Looking forward to my new iPhone4.
