No... My Beloved Nokia 3220!

So, Today as i was sending something to my friend via MMS my phone went stange…

A List of System files appeared… like, PreferedTones and Prefered images and some other file names that my kepboard cannot create…

An Example:
/Images/ [FONT=&quot]£[/FONT][FONT=Verdana]Â.Z[/FONT]

and its been bugging me since!
