We've gotten a few emails this morning from TiPb readers who think signal strength might be a factor in the dreaded iPhone 4 "hold different" reception problems. Last night when testing at home, they could kill the signal by holding the iPhone 4 over the lower left side. When taking it out of their homes and onto the streets, it didn't seem to happen any more.

Could signal strength be a factor? If you're having the "hold different" antenna band reception problem, have you tried it outside in a high signal area yet? If so, any difference?

UPDATE: Jeremy says we should mention reports like Engadget's, where they get better reception with the new antenna. Jeremy is almost always right, so we're mentioning it. Bottom line seems to be: strong AT&T signal, and the new antenna does wonders. Poor AT&T signal and covering the antenna, there's no hope for you.
