Hi everyone, I recently switched from chatr to fido on my jailbroken iPhone 3GS but when I did the phone would not recognize the Fido sim card. The representative at fido told me that maybe it was because the phone was unlocked, so I tried to unlock the phone with ultrasn0w 1.2.7 (my 3G was on and my sim card was inside). When the process completed, my phone finally recognizes the fido sim in the carrier section but on the top left hand side corner of the phone it says either "Searching/No Service" all the time. I just wanted to know if there was anyway to fix this so that my phone could work again. If anyone could help me find a method that doesn't result in me losing all my texts and other data on my phone I would really appreciate it. Here is my info:

Model: iPhone 3GS
Carrier: Fido
Version: 4.3.3
Modem Firmware: 05.16.02

If anyone could help me that would be great. Thank you.
