I need help with my wifes pearl, ever since we upgraded the firmware to 220.127.116.11, she has been having A LOT of glitches and issues with the text messaging, and with the blackberry messenger. So I would like to know how to downgrade to Tmobile's version firmware 18.104.22.168? If anyone can help me it would be greatly appreciated, so we can take it back to Tmobile.
