Best jailbreak for 4.2.1?

[RBloom83]

I have an iPhone 4g with iOS 4.2.1 and wanted to know which is the best jailbreak program for it? I've tried limera1n but they have not updated it yet to support 4.2.1 so any suggestions?

greenpois0n for untethered 4.2.1 jailbreak.

I've had greenpoisin and it sucks. Nothing on cydia or winterboard work. Any other suggestions?

Prehaps it didn't install correctly the first time? My iPhone 4 runs greenposi0n great on 4.2.1. Cydia and winterboard work fine.

I just installed it again hoping things had changed an still most of the themes and whatnot I have tried installing through winterboard won't show up on my phone...

The themes may not be compatible with 4.2.1
