So a question about this.  Why are we checking the netreg atom?
Shouldn't we be checking the gprs atom's attached property?  But this
brings up an even more interesting question, do we even need to assume
that we have to be attached to the cellular network to perform these
operations?  We could in theory go over wifi.

Thoughts?

Rest seems reasonable to me.
