I'm also having an issue with the alarm not going off. Worked on Tuesday just fine. Wednesday didn't go off. Thursday didn't go off. So when I woke up, I tested it by resetting it for 5 minutes later, and it worked fine. Thought it was just weird. But, last night I set a second alarm for 15 minutes after the first, so I had two alarms set for 430 and 445. This morning, neither went off. So, testing, I reset one for 545, and it went off just fine.
Does my phone just think it's too early to get up? I've verified the sound is maxed on the alarm, the ringer is on, everything is on. Like I said, it works when I reset it for a few minutes from now, just not when I let it sit overnight.
Any suggestions? I never had this problem on my G1 or myTouch3G.
Thanks,
Nathan
