ysince you cant see the screen its very hard to tell what you are doing, i suggest you take the battery out and put it back in, this should reset all the time and get rid of your alarm, but your best option is to get a new phone! bcos u cant see what ur doing!?
I recently brought an Ipod touch 4g, my friends have got older models of the ipod touch and they have jail broken it, they've told me its a great experience. Now I'm not sure weather I should do it or not, Please Help
Thanks
