If you have an iPhone no doubt you are having some fun with the applications it comes with. This handy little smart phone may replace every gadget you currently have to lug around and then some. Some apps are handy, some obscure, some addictive, some are free and some are well worth every penny. To begin with, the iPhone is a phone, so it may well replace your landline. If you use your cell phone as your main number you never need to change your phone number again. It doesn't even matter if you move to Florida or Virginia or California, you don't have to switch your area code or anything. As long as you are receiving calls from the same carrier the minutes don't go against your monthly limit.

The iPhone also comes with a digital camera built right in. Most plain phones have this capacity, however you have to download the photo to a computer before you can do anything with it, besides view it. On an iPhone you can forward the photo to your own email, to a friend, duplicate or save it right there on your phone. The phone can text message like a plain cell phone, but also send and receive email. You can websurf on it, down load a movie and watch it on your iPhone. You may not think watching a movie on such a small screen is appealing. Actually, because you can hold the phone close to your face in a matter of minutes you tend to forget that you are looking at a small screen.

One of the apps I use daily is the GPS system. Until I got my iPhone, the cheapest GPS system I saw was about $400 and it seemed small, like I might have trouble viewing it while I was driving. A phone IS small, but because you can lift the screen close to your face it is easy to use. The GPS updates constantly, showing where traffic is heavy because of accidents and offering alternate routes because it displays an entire map of the area. Back in the day, when I used MapQuest to map a route or even before that when I used to go to triple A for a "triptik" neither one had the capacity to update according to traffic.

The GPS system gives you the capacity to search for the closest Wal-mart for example, and then request directions to that location. Be prepared, even if the location is 150 miles away, trusty iPhone will give you the directions and an approximate travel time. It has three modes, walking, public transit and driving. Sometimes if I am looking for a coffee shop, and the place is located inside of a hotel, it is useful to change the search directions to walking mode. If you are traveling with a pet you can use the GPS system to search pet friendly hotels such as motel 6, and then switch to the browser mode to book your room. Some website have a mobile phone friendly version of their site, such as Facebook. You can download their application to your phone for free and access the site faster.

Another useful application that comes on the phone is the notepad. Now that I shop at several different stores it pays to make note of which one sells milk the cheapest, which one has the best variety of eggs, and so on. If you notate once on your phone that Whole Foods sells goat milk for $3.99, while Ralph's sells it for $4.99, you never need to hunt for a shopping list again, everything will be in one place: on your phone, which you would have with you anyway.

The calendar in the phone can be set up with every appointment you'll ever have, even years in advance. In addition you can create alarms to remind you of an event, an hour in the future or even a couple of days in the future. Set up a birthday as a reoccurring event and you will never forget it again. You can post dentist appointments six months out. You can load the address and directions right into the event description. It's all super convenience and much smaller than carrying a dayplanner.

Dictionary.com is free but not automatically on your new phone. Download this application and it will work even when cell service is not available. This dictionary has word root origins, pronunciations and usage examples. I find it to be the most useful dictionary on line, and better than many manual dictionaries. Generally I could say the main problem I have with digital products is the inability to view nearby words, but dictionary.com even includes those.

The phone comes with a simple calculator, but if you are like me and prefer the reverse Polish method of computing you can download the original HP application for a few dollars, or a close clone for free. I like to be able to do my own amortizing when I'm talking to a salesperson, don't you? The seventy dollar HP I normally carried around was taking up space in my little purse. Now I leave it at home by my financial papers.

This is silly but handy, there is an application that turns the whole screen into a flashlight for you. Handy when you are trying to fit a key into a car door or open the garage or just walk in a dark place. There are a variety of options, my favorite was free and looks like an incandescent light bulb. I guess programmers have a sense of humor. Restaurant apps for your favorite chains and franchises are super useful in Los Angeles. Most of them enable you to find the closest location of a Starbucks for example, or Baja Fresh and some applications enable you to place your order on line so it's ready to go when you get there. Used in conjunction with the GPS, you can get really styling. Impress your date! Get her to the movies and buy your tickets in the car from Fandango on line.
