i have the Motorola Q which is a windows mobile phone. I downloaded the app off Yahoo called Yahoo Go. When i run the app i can check my mail along with other things. When I clicked Options under Mail, it gave me an option to turn on push email and turn off pull email and vice-versa. My question is whats the difference between the two, and since that app on my phone isent running all the time, will one of the settings cause the app to be running all the time in turn losing me more battery time? Thanks in advance.
