I don't know, I'm worried now. I have my iPhone4 since yesterday afternoon, and so much I love about it. BUT there are problems. Not only does the reception drop dramatically when you touch these areas, and who doesn't when they hold the phone? But I am finding that if I put the phone in my pocket, I get about 90% signal loss. Meaning, as what is happening already, I'm missing calls! Why, because 90% signal loss, if you're not getting 100% signal strength means you have NO SIGNAL at all. I've missed several calls already.
Next is vibe, I don't know about anyone else, but I'm finding it doesn't vibrate as well as the 3G does. But also doesn't always vibe when the phone rings or you get an email when it is on silence! I was in a meeting all day today, the phone was on a hardwood desk in front of me, normally if a phone vibes it is loud because the wood makes it echo. Well, I got a phone call, and nothing, no vibe, nothing! I happened to pick up the phone 2 minutes after the call came in and noticed a missed call. NOT GOOD.
Finally is call failure. So far I have had 100% first time call failure. 100%! This afternoon I was trying to call my wife, I had to try almost 10 times for it to even DIAL OUT! My 3G had major call failures as well, but nothing like this.
I'm hoping today was a fluke and things will get better when the systems get back to normal after all the activations. Or if it continues I'll take it back in and see if I can get it swapped out and try another one. But it might be going back before 30 days.... but I ***REALLY*** don't want to do it, everything else is great (fortunately I don't use the phone part too much).
