unlock successful....but no service

[amar_85]

i successfully jailbroke and unlocked an iphone 3g using redsn0w and ultrasn0w to use with t-mobile. It works successfully once in a while but then the singal strength goes to 1 bar then searching then no service. I have the new software, version 4.0.2, and the new firmware, version 05.13.04. I just got this yesterday and i'm working 12 hours a day the next 3 days however any input would be greatly appreciated.

I also have 3g turned off and have tried restarting it, removing and reinserting sim, and turning airport mode on/off multiple times.

Hi guys, also having the same issue.

I recently jailbroke and unlocked my 3g running on ios 4.0.2, bought a SIM with my carrier today and I was able to make a couple calls. I had signal bars for a while.

When i went to disable 3g and cellular data in 'settings', that's when my phone went kaputz. Maybe the 'no signal' has to do with disabling data? I can't see how that can be connected though...

My wi-fi is working fine though. When I go into 'settings' to select 'carrier', it only lists 'Rogers Wireless' and 'T-Mobile'. I'm with Telus... should Telus be showing up in the 'carriers' option? Funny thing, because when I go to the 'about' section it lists TELUS as my carrier....


****EDIT******

Alright guys, I got it to work. I had originally disabled 3G and CELLULAR DATA in my settings, but I enabled 3G and rebooted my phone and now it recognizes my carrier. I guess if you want to disable 3G, you'll have to phone your mobile company to block it instead of disabling it in the phone's settings.
