Hi Everyone - my apologies if this has been brought up, I just got my iphone 4 and haven't been on these forums much until now. So, in my house my 3G iPhone always got 4 or 5 bars and my iPhone 4 largely gets the same, except when its asleep it seems to drop to one bar. I turn it on, see the one bar and by the time I get to launching the Mark The Spot ATT app, it has risen to about 4 bars. Anyone seen this? Is it simply a display thing or is the phone really losing signal. p.s. I have a bumber on and I can verify this behavior with my phone on a desk (not in hand).
