Is there any way of doing this as i hate the current one. It's just single beeps, which is really irritating.
Change Alarm Clock Tone
Yes, take a piss into the receiver and you should get garbled beeps.
Yes you can change this tone by using the program called extended profiles from psiloc.com and smart profiles by symbianware.com
Or world clock pro for multiple alarms and assigned tones for each. 😉
