  The iPhone was and still is an awesome phone. I love the design, the display is amazing and the apps are possibly the best selection ever. There are some downsides, however, those mainly being the signal problems and the cameras. Otherwise, it's still a great phone. However, if you can afford it, I would recommend buying a 4S or a 5 instead.

  Pros:

  - Revolutionary, high quality, full of awesomeness retina display.
  - Nice design with very high quality materials.
  - iOS ecosystem is unsurpassed.

  Cons:

  - Antenna-gate is not a myth, but not that of big deal.

  Summary:

  The iPhone 4 was the latest real innovative product introduced by Apple to date. It featured the best display on a smartphone ever (and still the best for the moment), and many other improvements in every area. iOS4 was introduced with it and for the first time ever multitasking was available in iOS. I think that this was the device that made the smartphone industry mature once again. The media inflated antenna-gate was true, but nothing to worry about.

  The iPhone 4 was Apple's latest big change to the iPhone lineup. It's still a competitive device in today's world and features the best display ever. FREE on contract seems a steal to me, so if you are short on cash and wan't to make your first steps into the smartphone world, this will run you for the money!

  It's a great phone and no issues the last 1.5 years. No antenna gate issue or speed issues. Its a very nice phone. The battery still lasts a day with used all the day, unlike some the phones i've had before(Sony ericsson) and all the apps you can download in the app store.

  The iPhone where I believe Apple really hit the sweet spot. Iconic design with beautiful materials and just enough heft to make you feel like you're holding a sneak peak of something from the future. Amazing battery life and a retina display that spoiled all other smartphone screens for me.

  Excellent phone, but you've already read that somewhere else. I've never found call quality to be that stunning (but this is largely dependent on your carrier) and I rarely get through the day on a single charge but I'm a fairly heavy user (GPS, CPU-intensive apps, FaceTime and so on will get you down to 1% in no time). Easily the best ecosystem & software on the market today (Android fans will disagree here but the form and functionality of iOS 5 is unbeatable) and the superb display and camera make this worth your cash.

  I've had the iPhone 4 since its release. Here is my breakdown of pros and cons:

  PROS:
  Great screen resolution, very readable and sharp. Color is very good.
  Physical design is really nice
  iTunes ecosystem is mature
  integration with Exchange is good
  Performance is fine

  CONS:
  IOS, even IOS 5, is feeling dated. Competitors have enabled desktops/UIs that are more "live" where there is more to the experience than a stack of dead icons.
  Reception is somewhat below average of other AT&T phones we have.

  I've been using the iPhone 4 on AT&T for over a year now, and it has been an exceptional experience. The design of the iPhone 4 is pristine, the issue come due to it's fragile glass construction, I have not cracked the screen, but I still worry every time I drop it, using aluminum would have been a better choice. The screen is the best on any phone I have used, save for maybe the Galaxy Nexus. The camera on the iPhone 4 is good, but not nearly as good as the iPhone 4S. The front camera is really crappy, I flip the phone over and use the rear camera if I want to take any self-portraits that don't look like absolute garbage. Reception–I've never had much of an issue with this, I have only dropped about three calls over the past year. The performance is great, I don't see lag anywhere. iOS 5 is really good, although a bit warmed over and boring, other than that though, it is extremely well designed and thought out as you would expect from Apple. I get about a day and a half of battery life on the weekdays and a day on the weekends. As far as the ecosystem goes, I have never not been able to find a given app on the App Store that I needed, so I'm not left desiring anything here. Overall, the iPhone 4 is still a great phone an it has been a pleasure to use it. I am looking forward to buying the 2012 iPhone, which I hope will have a slightly larger screen with a refreshed design and software.

  The best software, sharpest screen and longest battery life of any smartphone, hands down. The iOS App Store and ecosystem ensure you'll never run out of new apps to try. Apple's customer service is also legendary. The phone is now out-of-date thanks to the 4s, but it's still serving its millions of users well. AT&T's 3G network, however, is less than stellar in civilized parts of the country (Northeast, Southwest, anywhere with a population). This combined with Apple's lack of experience in making an antenna means you will experience your fare share of dropped calls. If you're primarily looking for an Internet device, the iPhone 4 is still a worthy choice.

  More than a year after its launch is a great great smartphone. Great design and great performance, his only fault , the poor battery performance.... like all smartphones.

  The software is still the key, beautiful and easy to use is the best way to reach more people taht do not want complications.

  Still a great phone, even after the announcement of it's successor.
  It's an iPhone 4. It's beatiful. It may be not very comfortable in your hand as Nexus S, and the glass back may get scratched, but you can't deny that this is one veautiful pice of engineering.
  Reception has some flaws if you are using 3G often. Otherwise, it's ok.
  Battery life is good when you compare it to androids out there. And even if you do not-I manage to make it home at 5 with 30% still left. Charging overnight, without doubt, is needed.
  Software and ecosystem are both great. Sometimes you'll hate iTunes, but after restoring your phone you will love your contacts and stuff already there, synced. Working like a charm most of the time.
  Your know what Apple's App Store is. Software - 10.
  If you're not into "open-source", don't need a phone to speak to and don't like WP software-wise you should consider getting this phone.
