I’ve found this application that lets you access Christianity SE on your android phone – https://play.google.com/store/apps/details?id=org.droidstack&hl=ru
The repository can be browsed using Mercurial at – https://code.google.com/p/droidstack/
So far it is looking good. Doesn’t offer all the features of SE portal but is simple and doesn't contain any bloat.
Don’t know if it’s appropriate to do this but just wanted to put it here so that more people can be aware of it.
If you have any such utilities or tips - software or otherwise - please share them below.
