In one sentence, describe what the following article is about: Cell phones come in different modes. The type of mode you want depends on how you plan to use your phone. Analog phones transmit signals throughout the air continuously. A wide variety of phones, from handheld phones to larger phones, come in analog mode. If you want to save money by opting for an older cell phone, go for a cell phone that comes in analog mode. Digital phones provide more security. Eavesdropping and number-stealing is prevented via encryption, so you may want a phone in digital mode if you plan to go online using your phone. Digital phones generally have clearer voice transmission and sound. The battery life is also longer. Most newer phones are dual mode, meaning they can be switched from analogue mode to digital mode. These can be great if you plan to use your phone in a variety of locations. When the signal is too weak to go digital, dual phones automatically switch to analog mode. There are essentially four different types of cell phone operating systems: android, iOS, blackberry, and Windows. The type of operating system you choose depends on your personal needs regarding the cell phone. Android is one of the most widely used operating systems. It's easy to customize, so if you're tech-savvy you may prefer an Android. The main disadvantage is that the design is updated frequently, which can affect usability. BlackBerries are great if you prefer a physical keyboard. However, BlackBerries tend to run slower than other operating systems. If you don't plan on using your phone for much beyond the basics, this may not be a problem. If you plan on going online a lot, you may want a different operating system. Apple iPhones run on an operating system called iOS. If you own other Apple devices, an iOS phone will be most beneficial to you. While iOS phones are less customizable than Androids, they tend to be more user friendly and have the most popular apps. Windows phones are relatively new, but are somewhat more versatile than regular smart phones. The display involves moving graphics and infographics, which may be helpful if you use your phone professionally a lot. You'll be holding your cell phone a lot throughout the day. Therefore, it's a good idea to go for a design that feels comfortable in your hand. Cell phones come in a variety of shapes, from square-like shapes to circular shapes. Pick a shape you feel comfortable holding. To get a feel of different cell phone shapes, make a stop at an electronics store. Experiment with holding a variety of cell phones. It's easy to forget a cell phone is a physical object. As you'll be using your phone a lot, make sure you find a design you're comfortable holding and handling. Cell phones come in three types: smart phones, messaging phones, and basic phones. The type you need depends on how you plan to use your phone. A smart phone is the most advanced form of phone. In addition to calling and texting, you can access the Internet, download apps, take pictures, and upload music. A smart phone is essentially a mini-computer. If you plan on using your phone for a wide variety of activities, the smart phone is the best option for you. A messaging phone allows you to make calls and send messages. It generally does not have internet access, although some do allow you to send emails. A messaging phone is one step below a smart phone. It's a great in-between if you're looking for a phone that allows for basic communication but does not need the added features of a smart phone. A basic phone just allows you to make calls. If you don't plan on using your cell phone for anything other than phone calls, you can probably get by with a basic phone. It will be cheaper and less overwhelming to use than a smart phone. How long do you plan to use you phone? If you're going to take your phone with you on long work days, you'll likely want a high-powered battery. Look for a phone with a long battery life over one with a short battery life. However, if you don't use your phone much, you can probably get by with a shorter battery lifespan. When exploring phone options, make sure to check to see how long each phone's battery lasts. Battery life gets worse with with time. Keep this in mind. Even if you feel like you can get by with a one to two hour battery, you may want to go for a slightly longer battery life.
Summary: Decide between analog, digital, or dual mode phones. Explore various operating systems. Look into different designs. Decide if you want a smart phone, messaging phone, or basic phone. Think about what type of battery you need.

In one sentence, describe what the following article is about: Nematodes are parasitic insect-eating round worms that feed on the grubs in the ground, providing an organic pest control method. Common nematode types include Steinernema Feltiae and Heterorhabditis bacteriophora. Place nematodes in the soil in late August or early September to begin treating the grubs for the next year. But you can apply nematodes as soon as there is evidence of Japanese beetle activity in your yard. Make sure the nematodes are fresh because they are living organisms. Water the ground before you spread them out, and keep the soil moist after you apply. You can also apply nematodes in mulch. For 50 or 100 million nematodes mix, use 1/2 teaspoon per gallon of water. Beneficial nematodes only attack soil dwelling pests, such as Japanese beetles, fleas, German cockroaches, termites, and ants. They are not harmful to people, animals, plants, or earthworms. You can purchase nematodes online, at garden centers, or at most major home improvement retailers. This method is effective for killing the pest in its larvae stage. You can spray the plants with Japanese beetle killer, found in most retailers and online. Sevin dust can also work, but it might kill beneficial insects along with the Japanese beetles. Some ingredients to look for when purchasing an insecticide are carbaryl, acephate, and permethrin. A Pyrethrin-based insecticide is a safe way to control pests on your plants while getting rid of other beetles in the process. Some insecticides are aimed at high Japanese beetle activity in your yard. Others are designed to be used in the early fall once the eggs have hatched and grubs are present. Make sure you read the label on the insecticide before you purchase it to find out what specific problem it targets. Neem oil is a natural pesticide that comes from the seeds of the neem tree, and is considered an anti-feedant because it reduces feeding of Japanese beetles when applied to the plants. Spray plants with neem oil to control the pests. Azadirachtin, one of the components of neem oil, can also repel and reduce the feeding of nematodes. Use caution using neem oil if you have nematodes in your ground to combat grubs. You can purchase neem oil insecticides online and at most major retailers with a garden center. Soap-detergent sprays are contact pesticides, with no residual effects. They are similar to household detergents, but are specifically designed not to harm plants like household soaps can. When applying insecticidal soaps, you must thoroughly wet the pest. Most pests needs to be sprayed every 4-7 days. The ingredient you are looking for in a spray is potassium bicarbonate. Even soaps manufactured specifically for insects can harm certain plants. Check the label of the bottle, or do a test on your plant before spraying wide areas or repeatedly.
Summary:
Use nematodes to kill larvae. Chemically remove grubs with insecticides. Use organic neem-based insecticides. Spray Japanese beetles with insecticidal soap.
