I got my new iphone 4 today and it does not have the issues as excited by a youtube video and likes. The yellow tint was figured out to be a glue that has not been fully cured or vaporized, etc. Ok, what if that same glue also created micro-gaps in the antenna area on the lower right? So, the holding hand covering the gap causes the signal to go down. I wonder, if this still be an issue in a few days, once the glue has finished vaporizing. Some phone may not have the yellow tint, but the glue vaporization is not quite done yet. Or perhaps, it is just a software glitch? People have made calls that lasted 30 minutes and no drop calls.
