I wonder why you'd need a specific chipset to have an RTC alarm. Couldn't it be added on the board independently? After having so many Nokias, I'm still amazed how so many phones miss what should be a basic feature.

I believe noone bothers to add additional hardware for this, but MTK has the hardware on-chip. I, too, hold old Nokias as a standard in this regard.

What's changing the IMEI useful for, other than to be able to use the phone once you've stolen it?
