I know there are a lot of threads regarding this but appreciate if someone can clear some things up since there are multiple tutorials:

Which unlock method is better: iclarified/geohot or ziphone? whats the diff between the two?
whats the best way to get to 1.1.3 with no problems such as the earlier ones e.g. sycn issues n all?
can i unlock using geohot method (iclarified) for 1.1.2 OTB, then upgrade to 1.1.3 using itunes, then use zibris method to unlock 1.1.3?any other way to do all this?

Lots of questions, yes. much appreciated.
