I think the mobile wallet should have XChat included, but I also think you should be able to download XChat separate from the wallet so that people who don't want the wallet can still be anonymous on the Internet.
Why not keep the wallet section anyway. people dont have to use it, but one day it might come in handy for them and they might go and buy some XC.
But that is just my opinion.
True some people might want that, but the wallet function isn't something that is too much of an inconvenience, Its not like download this....but it also has his bad thing but just ignore that, no it's download this for completely anon chat, also you can use it for complete anon currency transfer also, and having it doesn't really change anything
I think if you want XC to be able get on the iOS platform, you might want to separate it out first. Unless appstore approves the combined app too.... XChat can just be like a Firechat type separate app on launch to get some brand recognition.
