[1.1.2 OTB 4.6BL] update to installer 3.0 ??

Hi all, i have an 1.1.2 OTB 4.6BL jailbreaked, can i update installer to 3.0, or it will update the firmware too??:confused:

Ufff... you have done a really shallow reading... Installer is just an app, nothing to do with baseband, bootloader, firmware, etc.

Thanks, by the way, i was looking for a thread like this on the forum but didnt found it, and i needed a answer.
