Thanks to joeykrimfor this write up for the Epic 4G.



It is a simple root exploit patch released a few days ago which should work on all android > 2.0 phones.
it worked on my evo and works on the droid 2.

run these commands thru adb
adb push c:\downloads\rageagainstthecage-arm5.bin /data/local/tmp
adb shell
chmod 755 /data/local/tmp/rageagainstthecage-arm5.bin
cd /data/local/tmp
./rageagainstthecage-arm5.bin
exit out of the adb shell, and type adb shell again. this time it should drop you to # instead of $.
if it goes back to $, run the exploit again,
cd /data/local/tmp
./rageagainstthecage-arm5.bin
and exit out of adb and then adb shell again to see if its # .
if it doesnt work the first time, repeat 4-5 times and let us know. it should work!
