I've had this phone for about 3 1/2 years now. It was a amazing phone in the first few years, however, after three years, the phone's battery is really bad and iOS 8 doesn't run that smoothly. I am also not able to use many apps due to the aging components.

Excellent Build Quality; Good Screen Resolution (780p; Simple; Easy To Use OS; Easy To Use One-Handed

Small Screen (3.5"; Battery Not User Replaceable; Lacks MicroSD Storage Expansion; iOS Lacks Customization; Low Ram (512MB; Weak Processor; Low Storage Capacity (16GB Model; Weak Battery Life

The good news is the iPhone 4 is finally here, the bad news for those in the United States is they are still stuck with AT&T. Preordering snafus, long lines and activation delays aside many people wanted to be the first to own the latest Apple phone.

+Screen Looks Fantastic; +HD Video; +Muli-tasking added; +Improved Form Factor; +Email Message Threading

Still only AT&T in the States; Anecdotal antenna issues found; SMS tones still not fully customizable

While we have a hard time recommending an upgrade for current iPhone 4 users, the new additions prevent the iPhone from becoming antiquated in a quickly churning smartphone market.

Ultra-capable camera; Siri voice assistant is handy; novel; HSPA+ delivers speed boost; Same gorgeous Retina display; Solid; attractive design

Still nowhere near 4G LTE speeds; No expandable storage; replaceable battery; Fragile glass back necessitates case

There's something a little surreal about seeing "Verizon" in the upper left corner of an iPhone's screen. It signifies something monumental for those who have been waiting more than three years to get an iPhone that works on Verizon Wireless' network.

Solid 3G performance; Personal hotspot feature; Super-sharp Retina display; Excellent camera and 720p camcorder; Best-in-class App Store

Can't use voice and data simultaneously; Doesn't support global roaming; No 4G

The Apple iPhone 4S is a significant upgrade over its predecessor, and boasts numerous improvements, but what does it offer for photographers? Nigel Atherton examines the camera and photographic features of the iPhone 4S

Minimal shutter lag; Large; sharp LCD screen; Touch Focus; Additional features with Camera+ App; Excellent image quality

Placement of the lens takes some getting used to; No manual control of ISO and White Balance; A larger; dedicated shutter button would be nice

Do you want an iPhone, and only an iPhone? If no other phone will do, Apple's iPhone 4S on Virgin Mobile ($649.99) is a very good deal. But if you're open to the huge world of Android phones , there's no way to justify the massive price difference between Virgin's iPhone and its other successful...

The cheapest iPhone 4S available today; if you include the plan price

No 4G; Much more expensive than other Virgin Mobile smartphones

The iPhone 4 is a major upgrade from its predecessor, the iPhone 3GS, in everything from the camera quality to data speeds.

Beautifully designed hardware and software; Excellent

New antenna is a major

The iPhone 4 is a very worthy upgrade for most users from the 3G/3GS and the original iPhone. I have still not found a device on AT&T that I would rather have than the iPhone 4.

Fantastic screen; Much improved battery life

Glass front and back make cracking the glass twice as likely

The Verizon iPhone 4 is an interesting product for Engadget to review. Firstly, it's not exactly a new device (not in any outwardly noticeable way). From design, down to its CPU, RAM, and even cost, this iPhone is the same as the AT&T model...

Far fewer dropped calls than AT&T version; No Verizon crapware; It's the iPhone 4

Data rates slower than AT&T model; Hotspot interrupted by incoming calls; Poor overseas roaming options
