| Actually the issue *IS* related to dropped calls but not the way one might think.
The problem with dropped calls manifests most often when a phone is moving from one cell tower to another. Remember you don't have to be physically moving for your phone to transition towers in urban areas. Phones can move from tower to tower due to signal changes, loading, or multi-path issues.
AT&T's problem with iPhones has been the "talkativeness" of the phones on their signalling channels. The signalling channels are used for sending/receiving SMS and for phones to coordinate channel and tower swaps.
When the tower's signalling channels are all tied up by iPhones in the area saying "hey, I'm here", then other phones in the area experience degraded tower swap behavior, SMS issues, and other related issues.
So decreasing utilization of the signalling channels will make dropped calls due to congestion much less of an issue.

I'd rather unlock so that I can use a prepaid sim when I travel. It is obvious I don't have an iPhone. But I thought the case was sealed and that you couldn't replace the sim card without cracking the case and losing the warranty.
Edit: Never Mind. I looked up some pics of iPhone 4 on Google and see that the iPhone has a sim tray that can be opened to replace the sim card. I guess I was remembering all those stories about iPhone going sim free to lock users to Apple authorization on cell networks. | |

The sim card slot is at the top and can be opened by inserting a paperclip in the small hole to unlock the slot.

And in the iPhone 4 it's at the side of the phone and uses a micro SIM which is smaller. | |

Nah, it's rather easy, it uses a simple paper clip and you insert it into the hole by the sim tray and the tray pop's out with the Micro sim this way AT&T can replace sim's with newer one's if needed.

| | | | | | The SIM card is actually easily accessible on the top of the phone (in between the headphone jack and the sleep button) by using either the included tool or a bent paperclip or something of the sort, similar to old floppy drive emergency eject mechanisms.
Anything else in the phone of course (battery, flash memory, etc) is indeed locked inside the case. | |
|
| | | | | | No. You can get to the SIM on all iPhone models. The iPhone 4 uses a micro-SIM, which is a pain in the neck because few other devices uses it. | |

Get a sim cutter and an adapter when you want to use the SIM in other devices. | |

| I had my iPhone 3gs unlocked and Jailbroken, was using it in Europe until I get drunk 1 night and left it in a Bar in London  .
I ran back to my friend's flat and remotely locked it and wiped it. So said I lasted a week without my iPhone until I broke down and got an iPhone 4. To make a long story short... I want my unlock and jailbreak PRONTO. | |

unlock, is for the phonechip basically. it allows you to put in any GSM chip from any other carriar so you can use that phone in their system. | |

Apple isn't unlocking AT&T iPhones, even those out of contract. So you have to rely on hacks such as Ultrasn0w which use security holes in the baseband firmware to unlock the phone. | |

| Apple's Understanding of Basics.. For a company that thinks they're so sophisticated, they can't seem to get the basics of cellular communication understood that all other companies pass with flying colors..
Its pretty sad and funny at the same time.
The saddest part being that they kept blaming at&t for issues that may have been partly their fault congestion-wise, but certainly more Apples fault.
I have to say with Android on at&t, I have not had any issues and the data speeds (1-4.5mbps) far outreach that of EVDO in consistency and ms response (ping) is quite stable here. I can online game with tethering perfectly smooth (pings between 90-135 usually). On my Sprint Android its quite a bit jerky and laggy (pings 115-195+).

| | | Re: Apple's Understanding of Basics.. It's more of an area and coverage issue.
When I bring out my other AT&T phones I've owned over the years they have the same issues that my iPhone has. I have a Motorola V551, LG CU400, a Sony Ericsson, and even a freebie Nokia. ALL of them have the same issue that my iPhone has, even the lauded Nokia.
The only difference is call quality and call loudness. The Nokia has the loudest and clearest call quality.

I'm not saying your particular problem isn't caused by at&t, but the iPhone's "chattiness" affects all other devices on the network. Phones don't get an individual control channel. The channel is shared by all devices connected to a given site.

| | | In my location Sprint 3g on my Evo is WAY faster than my neighbor's Android on AT&T. He just moved here and complains (loudly with expletives) daily. Which one is better is largely based on location. 3g is 3g and wireless is wireless. Your results may vary.  | |

| Re: Apple's Understanding of Basics.. This is true and I agree with that as Sprint seems to be consistent EVDO coverage-wise overall throughout the states, but as far as capability goes, it seems EVDO is not as consistent jitter-wise and speed-wise.
I also will say that CDMA call clarity is MUCH better and louder than HSPA/W-CDMA anyday.

| | | | | Re: Apple's Understanding of Basics.. Interesting. Maybe where you reside and use your phone CDMA call clarity is a little better, but not where I live. Also, I've used ATT service between your neck of the woods and Key West (many, many times) with great results. Don't forget how much spectrum ATT has in Florida- it's almost *obscene* how much there is . [In your case are you referring to using a CDMA phone indoors(?)]
FWIW, I've loaned my ATT phones (2 different Nokias & 1 ATT Tilt) to friends with Verizon and Sprint so they could compare service. Nearly all of them said ATT was either a little better or much better call quality in general. Dropped calls were about the same in frequency, whether it be rush hour or off peak. My friend with the whole shebang on Sprint for a great price griped that she would never pay extra just to get an iPhone but was surprised that ATT could work very well with other handsets.
My wife's iPhone 4 seems to work better at holding onto calls than her 3GS did IMO and E. Having Airprint now is also a neat feature that makes me want to upgrade at some point. | |

None of these issues ever happened in Canada (to which I can attest from personal experience) or Europe despite heavy iPhone adoption and similar population density. In other words, this is entirely AT&T's fault, not Apple's fault.
I'd also question relying on on Nokia to confirm problems with their competitors phones. That's like relying on Microsoft's "Get The Facts" campaign for all your information on Linux.

| Re: Apple's Understanding of Basics.. 2 words for that: Frequency Differences. Can't really make a comparison with the rest of the world when frequencies here are way more overcrowded and congested. Being as Europe is predominantly 2100mhz (not sure about Canada) vs at&t 850 and sometimes 1900mhz here. Apple cannot expect results to be exactly the same on different frequencies and need to adjust accordingly.
Its true about Nokia with regards to competitors but if Apple really is coming out with such fixes, then its clearly fact. They may not be entirely noticeable in Europe with what I said with the frequencies and spectrum availability, but I bet issues exist there as well.

| | | | | Re: Apple's Understanding of Basics.. No that's not it. A lot of AT&T's 3G network was on 1900MHz which is where they had problems. They've been switching it to 850MHz which has more coverage per cell site.
The reason that the network in Europe is better is because they have more and smaller cell sites. | |

Now it is, only because they changed it and swapped spectrum with the EDGE network due to complaints from 3G users. | |

kudos:16 | said by fifty nine:The reason that the network in Europe is better is because they have more and smaller cell sites. In other words, the European providers hadn't underprovisioned their network as much as AT&T? That kind of just reinforces the point that AT&T just didn't have enough capacity to handle their customers.
I'll note that Rogers, the primary iPhone carrier in Canada until Bell switched to HSPA, uses 850 and 1900 for their 3G network as well. I believe Bell does as well. In other words, all the Canadian carriers are using the same spectrum as AT&T, and haven't had issues despite similar population densities to many American cities. The Island of Montreal has a population density of 3,716/km^2, while Ville Marie (the burough of the City of Montreal containing downtown among other things) is 5,443.5/km^2.
Boston, for comparison, while admittedly a smaller city in terms of population (although the metro area has double the population of Montreal's), is 5,144/km^2.

| | | It's not all Apple's fault either. My brother lives in Europe and he has none of the iPhone issues publicized here. I imagine it's a combination of a network engineered for minimal standards and a phone that, to its own peril, expects the carrier to do better than just enough to get by. | |
