Smart phones are taking over the cell phone market, but which smart phone is the best? How do you know whether the Samsung blackjack is better than the Cingular 8525 or vice versa? The guidelines posted below will help you make the best decision when it comes to buying a smart phone.

One thing you need to compare is global navigation. If you are trying to decide between the Blackberry Pearl and the Cingular 8525 then check out global navigation and see how easy it is to navigate the functions. You want it to be easy to go back and forth between functions in the phone and don't want to lose your place when checking on something else. As a result you want to make global navigation one of the top things to check when looking for a smart phone to buy.

Another important aspect is ergonomics. You want a smart phone that is easy to hold and that has buttons that are easy to press and navigate. If the phone doesn't feel good in your hands and is not easy for you to maneuver and handle then you will eventually be fed up with the phone and simply frustrated. So, make sure you feel the phone in your hands and know up front how it feels before you make a purchase.

You should also check on functionality of the device in regards to personalization. You want to be able to personalize your smart phone and have it work for you so this is also important to check out. Usability is another aspect and you should look very clearly at the graphics to see if they are clear and understandable to you.

And, once you decide on one of the three phones mentioned above you will love that you can also buy Blackberry Pearl accessories, Cingular 8525 accessories, as well as Samsung blackjack accessories. No matter what you need for your smart phone you can find it online. The easiest thing is to just do a search for accessories for your particular smart phone and you will find all kinds of things to buy!
