The update has already been applied by some lucky souls. It’s an over-the-air affair, so you’ll be able to perform it even without hooking your phone up to a computer, but keep in mind that, as with all OTA updates, the rollout may be staggered. That means that you may not see the update yet. In that case, don’t panic. Just remember that a few more days (or hours) of waiting are nothing compared to the ordeal you went through over these past months.
With Ice Cream Sandwich already out on the Samsung Galaxy Nexus, the next big wait (for the ICS update, of course) is about to get started for Droid Charge owners. That’s in case Samsung and Verizon don’t decide that ICS is just too cold for the Charge. We’ll see.
