Please help! No signal after jailbreak using redsn0w

[apexone]

I bought a iphone 4,Version 4.3.3 (8J2) and firmware 04.10.01
This phone is locked to Bell in Canada
I had it jailbroken with redsn0w, and then unlocked it with ultrasn0w
Everything looks going well, but there is only one bar siginal and it doesn't let me to make call after jailbreak and unlocking.
Can any body help me?
Thanks in advance

It doesn't work because you can't unlock the iPhone 4 with Ultrasn0w unless it has baseband 1.59.00. On Cydia's Ultrasn0w page it has a list of compatible basebands. This is why it is important to read before you do things.

Currently, your only option is to use the Gevey turbo SIM.
