I built this and it went great. So far I haven't experienced any bugs that I can find. I don't do anything fancy like dialers or S2U2 so that may be part of it.
One footnote is if you have Alltel and MMS won't work with the LennySH cab then do this:

I'm not sure if GGuru got a chance to update it per my request or not yet but this is handy to keep around. Kudos go to metters for figuring and posting the fix.
