Interesting find regarding iPhone 4 signal loss while holding in left hand. I have two ip4's and both have the problem which can be repeated consistantly.
I added a Zagg Invisible Shield to one of my phones and I no longer lose signal. Not sure why, but evidently the problem is not just related to the aluminum band, but the glass as well.
