Should i upgrade my iphone (ios) to 6.0.1?

My iphone is a iphone 3gs new bootrom with ios 5.0.1 on it.
should i upgrade to 6.0 or 6.0.1.

i'm fine with any version just not below ios 5.

SHSH: 3.1.3, 4.0, 4.0.1, 4.0.2, 4.1, 4.2.1, 4.3, 4.3.3, 5.0.1, 5.1.1,
cydia says i have 6.0.1 but tiny umbrella doesn't.

remember the latest untethered is 5.1.1 but i'm not really bothered about jailbreak right now because the 6.0.1 one is almost out, just semi tethered. I don't care. Its just my iphone has been at bit slow and freezing, probably because i delete stuff, like photos and videos a lot.

i have my photos and videos backed up btw on my computer, away from itunes.

should i upgrade to 6.0.1, or should i stay at 5.0.1 (restore) or should i update to 5.1.1. Basically its this three firmwares. No ios 4. X.X

NO! Don't its apple users worst nightmare

Don't update it's not worth it. You say it is running slow. If you have the jailbreak on your computer and know how to jailbreak just back up, restore but don't update. This will delete the jailbreak and all you need to do is set up as 'device name here' in iTunes and jailbreak again.
