Hello, I am going to factory reset my phone. However, my question is since this is a complete reset will it also rollback to the version of android that the evo was launched with?? For example, I know have version 2.3.5. Will it roll it all the way back to 2.1? I just want my data erased, I want to keep all my system updates including whatever updates sprint sent. Do I have anything to worry about?

Also, the evo I'm resetting is deactivated. Once the reset is complete will I be able to fully use my phone without the need of a sprint connection? I have wifi so that will do.

Your phone will retain the 2.3.5 update, only your data will be gone

all your data will be gone, but any OTA's or updates will still be there.

Also if you have a custom ROM installed, doing a factory data reset in the settings will put your phone in a boot loop. You'll have to go into recovery and erase data, etc., that's only if you've installed a custom ROM like CM7,9 or an AOSP ROM.
