I walked out of work and pulled my blackberry pearl out of my purse. I clicked the *call button to unlock the keypad. After clicking this over and over again trying to get it to unlock I finally put it back in its holder. I got to the grocery store and the phone was unlocked when i pulled it out of its holder. I went to my text messages and it started spazzing out. Everytime I scrolled up the phone would go my call screen and type Q or W. The buttons werent working and it was sending blank messages. Please help! I didn't drop the phone or get it wet. Is there a way to reboot or reset it? Is it possible that it is the SIM card...? Mine is very old.
