[Q] Solution for camera bug topic

Hello...

I installed this ROM http://forum.xda-developers.com/show....php?t=2540838

There is a camera bug... but in the page 31, there is a update that promisses to fix this bug.

"ROM => http://goo.im/devs/Alberto96/I9500/C...CIAL-i9500.zip

Changelog :

- Fixed Camera
- Fixed Inverted Colors
- Updates CM Sources

Enjoy! "

My doubt is, when I will install this new ROM (update), Will I lost my data of programs, sms, etc? Or is only a update?

Thank you
