the green could be a little brighter if thats possible branding wise. and the background 1-2% more grey than white but i would have to see it on an actual phone. I can't wait to have this on my phone . thats what i have been waiting for for weeks.

That's something I've been thinking about a bit, given that XC's brand has the drawback of coming across as a bit boring and 50-something-ish.
XC's brand has the benefit of being professional, serious, and not being associated with the darkweb. But a little more energy, a little more of an upbeat tone, etc. might help.
Same goes for the press releases and marketing for XChat. It should be more upbeat than core tech-related releases.
I'm guilty of the old man jokes.

. You are absolutly right . energy is the perfects word. perhaps a brighter "lifelyer" green plus introducing an additional second complimenting color for some little accentuations. like a nice yellow works well with green. don't know . just suggestions.
anyway the layout and overall approach is an absolute hit.
Ha ha. Perhaps rather than "guilt", the term "credit" should be used. Nothing better than constructive criticism. :-)
If we end up releasing several separate apps into mobile marketplaces, it would make sense to differentiate them brand-wise, since each app would appeal to a different user base and would have a distinct function. So, while they'd all need to share similarities in layout and font choice, different icons and different colours are obvious ways to differentiate them.
