I dont think they can fix that. I believe its a hardware issue especially since the antenna is right there. Which means recall or Rebate one of the two i am sure. -MASTER
Not necessarily. I remember one Motorola iDen phone having a similar issue that resulted in a statement to the effect: "Some people are having issues with reception. Our engineers have determined that how you hold the phone affects signal quality... blah, blah, blah..." They went on to show a diagram that had very specific places to put your fingers and whatnot. They then sent this "Bulletin" out to everyone who had already bought one and slapped a sticker on every new one made from there on out. Maybe you have to be wearing a turtleneck sweater or suttin' when ever you use the new iPhone.
Gripping any mobile phone will result in some attenuation of its antenna performance, with certain places being worse than others depending on the placement of the antennas. This is a fact of life for every wireless phone. If you ever experience this on your iPhone 4, avoid gripping it in the lower left corner in a way that covers both sides of the black strip in the metal band, or simply use one of many available cases.
