I have a JB/Unlocked 4g on 4.0.1 with firmware 1.59. What do I gain if I were to upgrade to 4.2? Just trying to decide if it is worth the hassle.

Well, the full version history is here:

Take a look and see what you think.

Also, since you say you're on baseband 01.59.00, make sure you're familiar with @notcom's method of keeping your baseband at 01.59.00 using TinyUmbrella (and therefore your unlock) if you do decide to upgrade:

Basically, coming from 4.0.1 you get Gamecenter (kind of an xbox live/steam type thing; see your standing on leaderboards), HDR Photos, AirPlay (Stream videos, music, and I think photos over Wifi to your AppleTV or AirTunes speakers), AirPrint (print from your device over wifi) and also some other stuff like battery life improvements.

Basically, I'd say yes. =)

You also get free with 4.2.1 If you lose your phone you can login to this website and itll show you on the map where it is. You can remote wipe it, put a lock screen on it and send it a message so if someone has it they will see it and call the number that you type in. Its free with 4.2.1. Other wise it would have cost you $99 a year with any other iOS :)

I ungraded for this feature mostly. And waht gomango typed is good stuff too. :)
