Yes, there is. (It used to be a lot of work to root the phone, but it is no longer.) This is the app: https://market.android.com/details?id=net.andirc.erisrooter&feature=searc h_result#?t=W251bGwsMSwxLDEsIm5ldC5hbmRpcmMuZXJpc3 Jvb3RlciJd
1. Install the app on the phone
2. Run the app and read the screen carefully - the developer wishes for you to make a contribution to a youth group of your choice, I believe, as payment for the app
3. Shut the phone off
4. Turn it back on
5. Turn it back off
(It's important to do all 5 steps. Many people skip step 4 and 5 and wonder why it does not work. In order for the root exploit to take, the phone must be restarted normally before you try to start custom recovery.)
Now you can start the phone in Amon_RA custom recovery by holding down the VolUp key when you reboot. Go to the Backup/Restore menu and Nand backup your phone. When that is done, press VolDn to return the main menu.
From here, you have a couple of choices:
a. Flash a zip from SD card and choose the rootme.zip file that was installed onto your SD card by the 1-click root app, which will give the stock ROM the SU utility and the ability to run root-only apps.
b. Flash a custom ROM to replace the stock ROM with something better. By installing xtrSENSE, you can have a close-to-stock ROM that is overclocked and also gives more space for apps. Or, you can install a Gingerbread ROM like CondemnedSoul's CM7 ROM. They are here:
[ROM][GPL][3/15/2011] xtrSENSE5.0.1 [cache2cache,apps2sd,oc,jit]-HTC Sense - xda-developers
[ROM] 11/19/11 Condemned CM 7.1 V21 (2.3.7) Splashed with ICS - xda-developers
And, starting with this fourth post in this thread
, you can find basic instructions for installing either of these ROMs.
