Here is a great application from the folks at Toysoft that caught my eye the other day mainly because of the fact it allows you to set different ringtones for specific times of the day. So say for example you are at work and you want to just have some nice basic ringtones for the possible business atmosphere you may be in, you can set it so that it will only play those tones. Then let's say you get off of work and you wanna kick some Flo Rida or maybe you'd like to hear some Steve Miller Band while you're away from the office, you can do that too.
Aside from setting "time of day" ringtones you can also have it set to play random ringtones as well. All you need to do is assign a folder with specific ringtones in it and set it to random and away you go. Next time you get a call you never know what's gonna play, unless of course it's a contact that you have assigned a ringtone too, as it does not change those ones. RandomTones is available for the BlackBerry Storm OS 4.7.75+ and comes with a free trial. After the trial it will cost you $4.95 in the Shop CrackBerry App Store.
