Newbe with a question

[PRW6969]

Morning all,

I was researching the Epic 4G and found mention in the reviews of something called "One Click Root & Recovery". What is that and how does it affect the phone? Is it a mod to the OS and are there other mods that I need to learn about? This will be my first smart phone, and I want to learn all I can before I commit.

Regards,

Paul
