app needed!

[tom_ch66]

hey i need/want a app that allows me to changed and modify a sms like this

sender: nuke
to: recivers number

and the recivers phone will say that nuke sent it and display nuke insted of a number... so they cant reply if they dont know who sent it....

i heard that kinda things exist... and i kinda want a app :P

cant i change the number im calling from to something else also? with a app? it would also be fun!

thanks yall!!!
