I've got Cydia but my still no service.

**nodgie** · 12-06-2012, 12:53 AM

I have an iPhone 3GS which I've being trying desperately to unlock. At the moment I have iOs 4.1 installed, I can access all my icons, use WiFi, and have Cydia, however when I insert either my O2(UK) sim or LycaMobile sim it still reads No Service. I used RedSn0w to unlock it. Any help would be greatly recieved.

Device info : (from Settings > About)
Version: 4.1 (8B117)
Model:Mc131B
Modem Firmware: 06.15.00

Like I suggested in the other thread u have. Purchase a hardware unlock online. Easy and permanent unlock.

The issue is redsn0w jailbreaks, not unlocks. Ultrasn0w which is available in Cydia can unlock. They are two different things. Simply installing Cydia won't unlock if you don't install ultrasn0w or the right apn for your carrier.

You have the iPad baseband so you should be ok once you install ultrasn0w but you will lose your gps.

I applied to O2 for the unlock code, they should send it as the handset is now out of contract. Fingers crossed. thanks for replies

I’m confused. I’ve heard all along that European GSM phones were all sold unlocked - apparently that is not true?

I installed Ultrasn0w from inside Cydia, inserted my sim but it still reads No Service. I swiched Airplane mode on/off, still no Service. Just to clarify: iOS version:4.1 Base band:06.15.00

Re-flash the 6.15, then re-install ultrasn0w

google how to get into DFU mode, open up the redn0w version that matches your current iOS, somewhere in there is an option to install ipad baseband, choose that and let it do it's thing.

Thaks for the response. I know how to go into DFU mode, doing some googling I found that I need RedSn0w 0.9.9, can anybody point me to a download link?

Edit: I found it :

I hope this is useful to someone
