I don't follow, wouldn't it at least indicate he was still alive enough to turn it on and off ? What are the other ways to read this ?
The signals were weak, so the phone was probably near the range limit from the nearest tower. Something may have changed to allow contact for a short period of time.
<PURE SPECULATION>
Possible reasons allowing the contact:
* Phone was turned on by living human.
* Something blocking the signal was moved away
- pack turned over (by human, wind, or avalanche)
- snow cover removed (by human, wind, or avalanche)
- human carrying the phone exited snow cave for a few minutes
- human body moved out of the way (still alive and moving, wind, or avalanche). There is a reasonable chance that the phone was being kept close to someone's body to keep the batteries warm.
* Changes in signal propagation--the signals were simply stronger for a while.
Possible reasons for losing contact:
* Phone turned off by living human
* Human went back into snow cave
* Batteries ran out
* Batteries too cold
* Water got into phone
* Phone covered up by something that blocks the signal (human body, pack, snow, snow build-up on roof of snow cave)
* Phone avalanched and buried.

And of course, simply because Nextel was able to contact the phone does not mean that there is a live human nearby. There has to be evidence that something intelligent was done with the phone.
All of the above reasons are PURE SPECULATION. The ability to contact the phone for a short period can be caused by so many things that I consider it to be of little use to determining the climbers status. Nextel was able to get an approximate location for the phone--believed to be a snowcave near the summit--which could be very helpful to the SAR folks when the weather clears enough for them to ascend to the summit region.
The last ironclad evidence that they were alive that I am aware of is the phone call to relatives Sunday afternoon.
I personally believe that if they are well dug in, they have a reasonable chance of still being alive. But they only had a few days of food and fuel, so if alive, they will likely be dehydrated, cold, hungry, and exhausted. If they were not able to get into (and stay in) a good shelter (eg a snow cave), I think there is little chance.
Not trying to scare anyone, just trying to be realistic. It looks to me like the SAR folks are doing everything that is reasonable to do. The rest of us can only wait and hope.
