so yesterday at work, my iPhone 3GS (Running 4.0) appeared to have "dropped" signals COMPLETELY. i wasn't holding it or anything. it would be in my pocket, i would check the time and there were 0 bars. i would have 0 bars for about a minute, so i fired up safari to see what the deal was. i could still load a webpage and it was fast as usual. okay cool, but can it make a phone call? so i call my dad with "0" bars, no reception issues and sound quality was clear as a whistle. i was quite confused... but my phone was working. i was gonna upload this yesterday but i forgot. the newest statement by Apple reminded me here's a screen shot i took... it was loading the page, with 0 bars. and it loaded it pretty quickly.
