> **Some users have experienced poor signal and dropped calls when holding Apple’s new iPhone 4 in their left hand, which makes their palm cover a seam that separates the device’s two perimeter radio antennas.**

> When Apple announced the iPhone 4 [earlier this month](http://www.appleinsider.com/articles/10/06/07/apple_unveils_redesigned_thinner_iphone_4_with_two_cameras.html), the company revealed that the metal band around the outside of the device has breaks in it to allow the multiple antennas inside the device — for cellular service, Wi-Fi, Bluetooth and more — to establish connections. The larger metal piece on the right side of the phone serves as the GSM/UMTS cellular antenna, and the smaller portion on the left side is responsible for Bluetooth, Wi-Fi and GPS.

The reports suggest that the [issue is worse](http://www.appleinsider.com/articles/10/06/23/some_early_iphone_4_shipments_have_defective_screens_missing_bars.html) than the problem described by Walt Mossberg of *The Wall Street Journal*.

I’m a lefty, and I definitely have this issue with my new iPhone, but ONLY if I cup the phone in such a way with my left hand that my skin covers over the notch between the antennae. I generally don’t hold my phone that way, (I’m more of a thumb and fingers holder myself) so I don’t think it will be a problem for me.
Nevertheless, I hope Apple can fix this in software, or get the people who are affected by this new phones that don’t have this issue.
In general, my signal seems to be better than with my old iPhone 3Gs, though I’ve only had this thing for a few hours, so that’s not a scientific observation.
