Can you find for me good one mobile?

It sounds like you are looking for a mobile phone or cell phone. There are several good phones on the market. If you are just wanting an unlocked phone that can be used on most networks such as Verizon then here are the top three.
If you are looking for a good buy and trying to get the best cost effective mobile phone then the Verizon Wireless Razzle is a great choice. It is a CDMA dual band, digital camera, and digitial player phone. Everything you need all in one and for under $25.

If you want something that has a little more durability to it then go for any of the Samsung line and especially the Instinct S30. They have up to 276 minutes of talk time, CDMA, digital camera, and a digital player for around $100.

The iphone is also a good mobile option but consider that the data pack for the phone to work properly does cost a bit more.
