You're Doing It Wrong
There's no great fix for the iPhone 4 reception issues right now. Here are the best pseudo-solutions so far.
What is going on?
Depending on how you hold your iPhone 4 during calls you may or may not notice your reception drop. Some haven't seen it at all, but many of our readers and our staff have definitely experienced it while browsing, emailing or using apps. We think it has a bit to do with your initial reception and people in stronger coverage areas are affected less. But we're also pretty sure — and Apple confirms it — that touching the antenna does affect things — whether or not it has the final result of killing calls or speed of data connection.
This is how Apple explained it:
"Gripping any mobile phone will result in some attenuation of its antenna performance, with certain places being worse than others depending on the placement of the antennas. This is a fact of life for every wireless phone.
With our past devices, the antenna performance when the phone was held in a certain way didn't seem to be an issue or stand out in particular. But with the iPhone 4 we're definitely seeing an effect, particularly when using data or tapping away on our on-screen keyboards."
Stop holding it wrong
Apple has explained that the iPhone 4 reception issues end when people just plain stop holding their devices the wrong way:
If you ever experience this on your iPhone 4, avoid gripping it in the lower left corner in a way that covers both sides of the black strip in the metal band.
This explanation does fit with the user reports we've received, but the solution isn't exactly comfortable. It's awkward to avoid touching the antenna points on the iPhone — especially because the glass on the phone's back and front is extremely slippery. The bottom portion of the phone just seems like a natural place to hold the iPhone 4 in order to avoid dropping the gadget.
The additional problem is that when you hold a phone for data usage — browsing or apps or email — you're going to almost have to touch the bottom and sides at the same time. Especially in landscape mode. This is a major problem for smartphones.
