Why would a Tilt have to be manually set to a network?

[losborn]

A friend of mine with a Tilt will find it showing "no service" fairly often. He has to manually set it to the network to restore service. Tech support thinks it's the phone, but I've never heard of this before.

Anybody have any ideas?

Could an unlock gone wrong cause this?

Hi, I am having the same issue after I have unlocked the phone. Apparently the Tilt constantly searches for a signal and it eventually gives up and I have to manually monitor it for proper network connectivity. This is a real pain. Is there a way to lock the phone back to it's original setting?
