7110 is a good phone but it is a bit outdated and big. Nokia has phased it out. But this phone has a fairly good battery management and reliable to use. If there is one is avalible in the market and you would like to use it then I will recommend this phone.
The pros of this phone are the Navi Roller, Easy navigation. protection of the keypad from being pressed accidently, Big display, IR port for connecting to pc, etc
The cons of this are Big size, avalible in single cover, bit outdated, does not support picture messsages and the antenna
