Hmm... makes sense. Is it a standard RTC chip with a limited number of hardware alarms, then or something more complicated? I have at least on one occasion set a good 25 or so alarms on the N900, and I haven't ever reached a hard limit in software. Any info? (A datasheet link would be excellent, if you have it handy - or an IC #, for that matter)

On the topic of annoying alarms, though, my dumbphone takes the cake with that, I think. You can only dismiss an alarm (e.g. without manually unsetting it in the config) when it is ringing, and not when it's snoozing in between rings. This would be fine, except that it will only snooze a certain number of times before turning off entirely. That would be fine, except that in that case, while the config says the alarm is disabled, it actually isn't, and will ring at the same time the next morning unless you manually set it and unset it all over again. :/ *sigh* Also, when ringing, the modal alarm dialog covers the system clock, and only displays the time when the alarm started ringing - so if you sleep through a few rings, you might well think it was half an hour earlier, and be late... </rant>
