poor signal causing problems?

[superman651]

I don't know if this is the problem but I seem to have problems with my phone with performance and application operation. It appears to give me problems most of the time when I have a poor signal either in roaming or Sprint. I also notice that when I use my alarm application (G-Alarm) with a poor signal, the alarm is sporadic about going off in the morning. It might be realted to the program and not the problem I'm talking about or course. Also the windows 4 color (hour glass timer) seems to just stick in the middle of the screen at random times also. Has anyone had similar problems? Can a poor signal cause problems for the vogue? I really appreciate any input. I have to be in this area with a poor signal on a weekly basis.
