Erase all content & settings on original iPhone

[johnny football hero]

I came across my old original iPhone that I want to pass along to my mom to use just for telephone calls. She does not text or use data. The iPhone is unlocked for use on t-mobile. I have a ton of pictures, games, texts, etc. still on the phone. I want to clear all this off of the hone before I give it to my mom. If I "erase all content & settings" will I lose the jailbreak on the phone? I want to keep the jailbreak for her ability to use it on tmobile.

Here's what I posted on another thread a few days ago:

When jailbroken don't ever, ever, EVER (did I mention ever??) erase all contents and settings. This will throw your phone in a respring loop and you'll be forced to restore through iTunes.
