Are there any good alarm applications for the X10i? Basically I use my phone as an alarm to get up for work. My old Nokia N96 I could set the alarm and then switch the phone off at night and the alarm would still go off on time. This does not seem to be the case with the X10i. It doesn't even go off when the phones in airplane mode which is poor. I just don't want to have to leave my phone on overnight in case it rings and i wake up. Are there any good alarm apps that allows you to turn the phone off and the alarm would still ring at 6.30 for work?
