Guys the antenna issue on the i4 is completely blown out of proportion...When it comes to calling you will be fine as long as you do not try to intentionally touch the bad spot. The only irritating thing I have needed to get used to is when I am web browsing my middle finger tends to wrap around the phone and short the two antennae. I've just had to adjust the way I hold the phone...The retina display makes it all worth it...I will never be able to use my 3Gs again!!! Its seriously amazing!
Thanks for the heads up! Mostly use my phone on Wi-Fi, but good to know!
