P3Go with 3.55?

Hey folks, I looked for this info for several hours but couldn't find any reference specific about my case. So here is the deal:

I decided to JB my PS3 and went shopping. The P3Go had good reviews and a nice price tag, so I ordered one (haven't arrived yet), but reading further to understand what CFWs, OFWs and all else meant I came to the discovery that my PS3 is currently with the OFW 3.55, and all I have read about P3Go says it needs 3.41. So my questions are twofold:

1 - Will I be able to JB my PS3 with it if I upgrade it (the dongle, not the PS3)? If so, how? I haven't found on Gamerbox any info about 3.55. Those tutorials already posted here about updating the CFW also cover the P3Go? Which CFW should I look for?

2 - In case question 1 is all a negatory, will I be able to use this dongle to downgrade from 3.55? Since I assume it's 'built in' (or whatever, the concept isn't all that clear for me yet) downgrader is for 3.50 only, I guess it is up to me to work some voodoo on the the dongle to downgrade. Or am I completely wrong and any pendrive will do it for downgrading?

Sorry if my questions seem a bit primary, I am looking to get my feet wet, just not there yet. Any pointers are greatly appreciated.

Thanks!

I am sorry, I seem to have posted on the General area, could a moderator move this to the Jailbreaking area? Thanks.

Have a PS3Go myself, havnt used it since I went to kmeaw's CFW alot better than having to mess with the dongle everytime you restart the PS3

As kpatm said. You don't need dongles anymore now that there is CFW

Really? Oh!

I was trying to figure if any of the PSGrades for another boards would work on the P3Go for downgrading purposes, since they added suport for the hexes on their latest update, but I will aim my research toward 3.55 CFWs then.

Thanks a lot!

Guess I will just keep the dongle around when it arrives, just in case Sony does anything funny.
