iPhone 4 signal strength

This is hardly a scientific study but I feel like I get better service with iPhone 4 than the iPhone 3gs. At least in Boston.

My office commute brings me to the Mass Pike for about 25 minutes each way. There has always been one stretch right before the Cambridge tolls where my iPhone 3GS would drop a call. Every time.

Yesterday I was on the phone and was able to keep the call going. It happened in the morning and at night. I thought I was dreaming.

Today I’m in NYC. I wonder if I’ll see an improvement here.
