Extremely loud pop inside apartment building, half the outlets (on the same curcuit) wont work in my apartment
Did you happen to notice if the transformer on the utility pole nearest to your house now looks shiny and brand new?  From your description, it sounds like it blew.  When this happens, for a few moments the voltage coming into your house could theoretically be anything (up to the high voltage side supply, usually several kilovolts), as the various windings within the transformer melt and short together.  Given that, it would be wise to check that all your devices are still functioning properly.  If not, check to see if your homeowners or renters insurance (if any) covers this.

You mentioned that some outlets were working fine while others were browning out -- how did you determine that?  If you're just going by which devices stopped working or dimmed/slowed down, that's not a reliable indicator, since many modern electronics with switching power supplies will continue functioning even on very reduced voltages, but other devices will not.
