If you are looking to buy a new cell phone then you may want to consider the Blackberry Pearl, although technically the Pearl is a wireless handheld device not just a cell phone. I found that although the Pearl is very expensive it is well worth every penny.
I found that this phone can do it all. I love using it to take pictures or my children or listen to my favorite songs. I can easily access the calendar or address applications as needed. I can check my email wherever I am and I can instant message my friends or search the internet when ever I feel like it.
The face of this phone comes with a full alphabetic pad and trackball for easily moving from one application to another. This phone is very small and I find that I lose it often in my purse. I have T-Mobile meaning that I don't always have the best signal but the Blackberry Pearl has crystal clear reception. All in all this is the best cell phone I have ever owned.
