I ran the Strength App, which we've discussed in previous posts about the iPhone 4 antenna issue. It is now showing a more nuanced level of how bad my home reception really is, but the bottom line remains the same. If I put on the Bumper, the thing can just barely make calls. Without, it can't.
The iPhone 4 just isn't a very good phone in low signal areas, which unfortunately is where my home seems to be. The difference is that my old phone never had a problem with those same signal conditions and my new iPhone 4 is crippled.
I know that Apple intended its update to change expectations -- fewer bars indicating less reliability -- but my expectations are that I should be able to make and receive calls in an area where I have already been doing so for the last three years, with Apple-branded equipment.
