iPhone, the famous powerful mobile in the world which used by hundreds of million people. Someone like its appearance, someone like its capability and also many people like its games and media functions. However, there are some opposed sounds to this smartphone such as its temperature issue, dialing bugs, etc. There must be more than five cool things about the phone - and certainly more than five things that suck about it. Therefore here we list the top 5 best and worst in my opinion. You know, just to help you decide if it's worth to hold one. It all depends on your ideas.

Top 5 Best Things about the iPhone
1. Sleek, Slim Design

Apple has packed a lot of phone into a relatively compact, beautifully designed case (4.8 ounces). The software is elegant too: Its only button always brings you back to the home screen, so you can never get lost or be forced to backtrack using a Back button through several layers of menus.
2. The Wonder of the Web

The Internet display capabilities of the iPhone beat out those of most other mobile phones. Websites reportedly look really good, even though they’re shrunk down considerably. Of course, Flash and Java do not work on the iPhone version of the Safari browser, so you don’t have a totally seamless Web experience. But Google Maps on the iPhone is also quite cool, and can come in handy when you’re in an unfamiliar city.
3. You Look Marvelous
The 3.5-inch display is bright, crisp, and easy-to-see. Reviewers have reported that video, though tiny, looks amazing.
4. Check Your Voicemail

The ability to listen to voice messages in any order, regardless when they came in, is going to save a lot of people a lot of time. (And make it that much easier to ignore messages from people you’re trying to avoid!)
5. Scratch-Resistant Glass

Sure, the glass face of the iPhone gets smudgey. But it’s easy to wipe off. Scratches, on the other hand, as every iPod owner knows full well, are much harder (or even impossible) to remove, and the folks who have reviewed the phone so far all report that their phone didn’t scratch, even when regularly thrown into pockets and purses with keys and other items.

Top 5 Worst Things about the iPhone
1. Too Hot to Use

Not only one people found the problem that the phone gets very hot while using the GPS and 3G of the phone or being plugged in. So far Apple has not responded except for blaming hot weather or user negligence in their support article “Keeping iPhone 3G and iPhone 3GS within acceptable operating temperatures“. Notably, this article covers both the iPhone 3G and iPhone 3GS. It advises users not to leave the iPhone “in a car on a hot day” or “in direct sunlight for extended amounts of time“, and not to use “certain applications in hot conditions or direct sunlight for long periods of time, such as GPS tracking in a car on a sunny day or listening to music while in direct sunlight“.
So, is this just a general problem with the iPhone getting warm under high usage, or is there some hidden fault somewhere? What do you think?
2. Please Hold While We Connect You

There’s no one-step way to make a phone call because the iPhone doesn’t have one-touch dialing or voice dialing. Call us throwbacks, but at least one or both of these features seem essential to any modern mobile handset.
3. Limitations on video formats

Too bad there are a limited number of YouTube videos formatted for viewing on the iPhone. It only supports MP4 and MOV.
4. Limitations on Third-Party Developers

Apple made a big deal out of the fact that third-party developers can create apps for the iPhone by developing Web browser-compatible apps, and that all iPhone apps can access iPhone features, like dialing a phone number or accessing the address book. But it’s no great shakes for developers, who’d rather see a full-blown software development kit (SDK) and the ability to actually add application icons to the iPhone’s home screen.
5. Soft Keyboard Leads to Fuzzy Typing

Those who have so far reviewed the iPhone all reported having a varying degree of difficulty using the onscreen keyboard. It’s very tiny, so if you have large or even normal-sized hands, it can be tricky to press the right letters consistently. And punctuation marks are on a separate screen from letters and numbers, which is fine for text messages but isn't going to cut it for composing business-related email.
