Iphone 4 Reception
iPhone 4 has some reception issues when held a certain way, particularly when your fingers touch its lower-right side. Most smartphones have similar reception issues. The iPhone 4 is worse than both the iPhone 3GS and the Nexus One in this regard. When you cover the lower-right side of iPhone 4 with your finger, especially if you clutch the area tightly, signal strength will drop at considerable amount.
