x10i 1.6 to 2.1 upgrade for dummies

[#1]

Hi guys, my phone is a recent purchase and now that i'm sort of confident in navigating it I'm looking at upgrading it.Its an SE X10i, f/ware 1.6, baseband 1.1.25, kernel 2.6.29-rel semc-android@SEMC #2, build R2BA020, PAYG simlocked onto UK ORANGE.I have d/loaded PC COMPANION and it tells me that I am up to date. Thats me now at the end of my comfort zone as I am now just a (big) tad confused with rom,s, basebands, flashing etc.Is there a simple plain english tutorial that I could clue up on without any side tracking to (probably) relevant points. Ideally along the format of e.g.download this this n' that, install this here and that there,activate this with that and look out for this when doing that.My main problem is that I am in a hectic environment and I find it difficult to maintain focus on anything of a technical nature without losing my thread.Sorry for the epic, I've tried to include all details I think relevant.

When I have looked up flashtool etc It gives me the impression that it is only for 2.1 Dos it work with 2.3? Forgive my ignorance but I have no pc access until very late in the day (night) so can only use fone until then and its awkward to follow links etc. When I get on pc am usually too tired to be very aware of what i'm doing.

Thanks, I'll get on that tonight. Is the flashtool complete or do I need roms from elsewhere ? Forgive the third degree I'm just trying to get my head in the right gear for when I can access pc. Oh and does it go through se companion or standalone?  Thanks again

You  need to download two things

1) flashtool

2) firmware
