I have a nokia 1100 as a back up phone (recently upgraded to my SE w600i), any way it has started to act funny. At home it is working perfect, but as I travel with it, it will start to go crazy. One second it will have a full signal, then the next second it will have no service. Then back an forth. Then it will work for a few minutes, then start all over. When it does get a signal, when I can call fast enough, it just beeps twice and then loses the signal again. It is fustrating.

I would like to give it to my dad (for a replacement of his broken phone), but not if it won't work outside my front door.

Anyone got any idea what is wrong?

Forgot to say it is through Cingular.
