Just thought id start posting the cool Iphone apps I've come across.
First one is from Safety Button Mobile

With the Safety Button Mobile App you will always have somebody know where you are. So If something should happen to you then your Iphone will contact your nominated person/persons.

With the press of one button you can do either or all of the following:
* text your position
* email your position
* make a distress call
* sound an alarm

With this little app Mum and Dad can rest assured that their daughter/son will be safe.
I guess it wont beat a can of mase but will let your family know where you are in case of an emergency.

Another feature which I thought was quite cool was that you can hook into wireless internet and access live radio streams, which would be definatly worth it if the price permits.
