Sure, I just wanted to make sure you had it flashed first.
Download the ROM you want. There are lots of good ones. I would probably pick just based off of the appearance since there's not a huge difference between them. Check the ROMs from Droidmod, Pete, Blackdroid, AdamZ and Chevy. They're all good.
Once you've downloaded, depending on which format you chose, do the following:
-If you chose an update.zip formatted ROM, make sure it is named exactly update.zip and in the main sdcard folder, not in any subfolders.
-If you chose a nandroid backup formatted ROM, make sure you create a Nandroid folder on your SD card. Unzip the nandroid file on your computer. Take the files and place them in a subfolder with whatever name you want. Make sure not to use spaces in the name. You should be putting the unzipped files into /sdcard/nandroid/xxxx where xxxx is the name of the folder you created.
-Reboot into recovery (hold 'x' on the physical keyboard and the power button)
-If you chose a Nandroid backup format ROM, select Backup/Restore from the menu
-First, I recommend selecting Advanced Nandroid Backup. This will backup your current setup in case of any problems. Just leave the default three items (boot/data/system) selected for now, and hit perform backup. Be sure to choose a name that is not too long and without any spaces or you may encounter errors. Do this even if you choose to use the update.zip method.
-Once that's done, on the same menu, select Advanced Nandroid Restore. If you put the files in the correct folder, you should see it as an option. You should also see the backup point you just created. Select the folder with the ROM files in it and perform backup with the defaults selected (data/system/boot). Let it go, and you're all done. Reboot into your custom ROM.
-If you chose an update.zip file, it's easier. Just choose the install update.zip option from the main menu in SPRecovery. I would recommend that, after doing your backup, you first do Wipe Data/Factory Reset and Wipe Cache before applying the update.zip. Note that you will lose your current data and will basically have a clean phone with just your SD card files remaining.
-In the update.zip menu, make sure you first select and click on "Allow update.zip install (deprecated)" or whatever it says there. If you don't, it usually won't work. It won't really acknowledge that you clicked it, it'll just flash for a second. That's fine. Now select install update.zip, let it go, and reboot.
