This discussion seems to pop up in multitudes on every forum and tech site. The answer just comes down to 2 things. 1. How much will it cost and 2. how much you want it. For me, it's a simple choice. I have a corporate plan on AT&T which allows an upgrade pretty much every year and I just sell my old 32 gig iphone on Gazelle with no hassles for anywhere between $160 and $200 dollars which means it costs me basically $150 to have the newest and latest, ...........and no convincing is necessary if you really want it.
Have you ever tried Craigslist to dump your used iPhones? I was able to sell my iP4 same day, $375 locally (Black/32gig). I was surprised...I actually was contacted by the buyer within ten minutes of posting it! I'm still blown away that people buy them at the price they do. Made my upgrade to the 4s AND 64gigs cost $24! I'm happy with AT&T where I am (we don't have Verizon or Sprint in Alaska)...so the "Two Year" contract is irrelevant. I will always need a cell phone.
Only if you like, it's more important that anything. But i'd rather like iPhone 4 more that iPhone 4s.
Huh?
The iPhone 4S fits Apples new business model of releasing a problem phone and enlisting the users to help sort out the problems. First launched in 2010 this new model has it's drawbacks. Last year I was forced to return several defective iPhone 4 models. So far this year I'm on my third BatteryGate return.
I can only surmise that Apple has increased it's profit by cutting back on testing & quality control. They know their customers will tolerate almost anything to own an iPhone. So far Apples right.
Sadly however it prevents me from endorsing the phone as I used to enjoy doing.
I don't think this is true at all. In fact, folks like you that continuously exchange phones because you are convinced there's some sort of anomaly... it's you that I would question, Not the Company. I've had iPhones in our family since day one. Every new model (I own a company as well, so I'm always eligible for the upgrade when they pop)...and the iPhone 4, I bought 8 eight of them for employees, my wife and son. None have been returned. None have issues. All still going perfectly strong! My 4s, same thing. No significant difference in battery performance between it and my 4. Maybe I'm lucky (I've only upgraded mine, not my employees...and my wife doesn't want to lose all her texts so she's holding tight

), but when I see these claims that people are returning them multiple times...I'm not a believer. Sorry.
As far as "Is it worth it?"...YEP! No question. If you're eligible for the update. I wouldn't hustle out to spend $800 on a new, unsubsidized phone...but if you can make a bit back on your iP4, you're eligible for the upgrade, by all means, pull the trigger! It's an incredible phone. Much more "fluid", the camera is awesome (a true P&S replacement), Siri is great!!! And I, like others, have noticed better connection rates, speedier downloads, and...to my surprise, a bit better "clarity" in conversations with people. Not sure if that's in my head, but it sounds better to me while conversing...both in the headphone section of the phone (holding up to ear), and the external speaker.
Love it! Best iPhone yet. Only the outside resembles the iP4. The guts, they've been re-done...and re-done Well IMVHO.
YMMV as always
