I live in a fringe area and ordered a Microcell a couple weeks ago before getting my iPhone 4 so I wouldn't have to walk onto my porch just to make calls. It came today and is set up and I noticed that the death grip doesn't seem to be effective while I'm on a Microcell, while at work and on normal 3G it does. Maybe this is a software thing as Apple has hinted that it might be, and if your already not getting "perfect 5 bars" that it reads into the attenuation more? Just a guess but seriously while on the Microcell I can hold the phone tightly around the left seam and nothing doesn't drop a single bar. Anyone else with one getting the same thing?
