Nah, I don't think so. With some clever programming and it watching maybe an average signal level over some period of time, I think it could do pretty well. The idea is to avoid HUGE battery drains over a moderate amount of time.
For example, if i'm at work in my office building, i get 0-1 bars of signal strength for 8 hours. It would be great if it detected after, say...10 minutes that my signal strength was in the crapper, and turned off the APN (or at least, account syncing) so I won't leave work 8 hours later with 5% battery life. But, if I wake my phone up, it will automatically turn the APN on so I can use data as I see fit.
But let's say I go out for lunch. The phone would either detect that I'm changing position/location via cell towers, or it would just regularly poll signal level and when it found that my signal level had increased by some delta amount over say...5 minutes, it would turn the APN back on.
I find that most of my frustration with this phone is with battery drain, and most of the drain comes from sitting in low signal areas for extended periods of time. If this could be accomplished (with configurable thresholds and stuff about time to average the signal over, etc) I think it would be an excellent addition to the customization-ability of android!
