I still have the original cellular radio firmware my phone came with (at least, I think I do. The baseband version is I9000BVJJPG). However, I've changed ROMs many times, and am currently using the latest AOKP Milestone release.
Is it safe to install the latest radio image from http://samfirmware.com (PDA: I9000JIJVG, CSC: I9000CELJVG), if it is meant for 2.3.6, and I have ICS?
