There's a whole thread about this.
Rag is going to move your post to that thread within the next few hours.
Anyways, go search Google for android 2.1 sdk.
Save that onto your hard drive. for windows hit start>computer>c:
Its the thing thar always starts with c:
Search Google for one click root method for epic 4g.
Download it and save it in the tools folder of the android sdk.
Hit start>computer>c:drive (hard drive)>android sdk>tools save it here.
Go find the one click root folder and open a file that ends with .exe
Its an executable folder, which is a one click version of a script (a bunch of commands)
When you get to something that says "restart desktop adb" or something like that enter your task manager.
Go to processes and end any adb processes, I had 2 running some people have 1
Then go back to the one click root folder and click on the adb file
Then sit back and wait for it to root
If it says phone undetectable make sure you have USB debugging on, still doesn't work try a different USB port.
After you root, if you plan on getting custom roms go search one click clockwork mod for epic 4g.
And do the same thing.
