1. Every phone with an internal antenna will experience signal loss when held. 2. Every phone is legally required to put their antenna on the bottom of the phone because of laws concerning radiation. Therefore, cupping the bottom of any phone IS NOT the right way to hold it, regardless of how natural it feels. 3. Does the iPhone 4 experience MORE signal loss than other phones when held in this manner? According to Anandtech, definitely more than the 3GS and Nexus One. But since there is no set standard on how much signal loss is acceptable and no laws regarding this, it is NOT an issue legally and therefore, Apple is not legally required to fix it (they can if they want to). 4. The phone DOES NOT drop calls regardless of how you hold it if you have a strong enough signal. 5. Does this make the iPhone 4 a poor phone for making calls? If you prefer to hold the phone this way, then yes. However, it is not defective, only poor and companies are legally allowed to release poor products. If you are dissatisfied, please return the phone and get another one. 6. But my store has a restocking fee! Then it is your mistake for buying it on launch day. Most people wouldn't think about buying anything else (phones, computers, TVs, cars, etc.) wouldn't first reading a few reviews but for Apple products, they get sucked in by the mania. That's nobody's fault but your own.
