Be careful not to update using the Sprint update process if you are rooted. Do you know the name and version of the Rom currently installed?

I recommend you do a little research online to familiarize yourself with the phone and software options available. is a very good site with instructions and available Roms.

Be sure to create a backup of your current Rom (safety net in case of issues) before installing or updating.

Basic Rom installation/update from recovery -
(1) Wipe Data, Cache & Dalvik Cache, and System (optional but recommended the first time)
(2) Flash the ROM
(3) Flash GApps
(4) Reboot the system (first boot will take several minutes)

Does this tell you anything.

You could be rooted but no custom ROM. A lot of people who use the "Revolutionary" method, have issues updating the stock ROM. Just do what a lot of folks have done: Download and run an RUU. It won't be hard to find. Hope it works! And also, your bootloader needs to be locked.

How do I know if I have a Custom ROM. Also is there any good step by step articles that anyone could point to me where I could update my phone to newest Android operating system. Also is there information when people ask about my phone that I shouldn't post? I don't mind posting all the info but also am a newbie and want to make sure my phone bill isn't a nice surprise by being cloned or something....LOL

You would be able to tell in the phone seetings. And as for an update to your phone, just use the RUU method. It's an .exe file that updates the firmware for you. Just Google search: "Supersonic RUU". You should be able to find a GingerBread one and all you do is download it, make sure your phone's bootloader is locked, and just boot into Fastboot. Make sure you have HTC drivers, and you should be good.

To find your current software version, click on menu button, system settings, about phone...you will see version and software information listed here.

There are a number of Roms available to you. You will need to decide what you want (features and functionality) and then select the appropriate Rom. It is easy to update / install a new Rom if you are rooted. website has many listed with screen shots, and instructions, so you can make an informed decision.

Just follow the instructions the developer provides and you will be fine.
