New to all this...
I've just got myself a 3GS running baseband 05.16.02, which is jailbroken.
- How do I find out which jailbreak is on my iPhone?
My friend told me to install ultrasn0w to unlock the device.. Which I did, before finding out on the net that it doesn't support my baseband..
Now, since I've done that (I've now uninstalled ultrasn0w, I've got "No service" all the time, and I'm using an o2 sim card at the moment, in an o2 locked phone...
Seems to have messed up my carrier all together, so how can I get it back?!
Hope you can help me! (Sorry if I've posted in the wrong section...)
Moved to ultrasn0w section (without more details I can only guess at the right section)

o2 in the UK will authorise "official" unlocking - you need to contact them and find out if you meet their pre-requisites for this. That is your best option.
I don't recommend the only other option available to you (install the iPad baseband to get ultrasn0w unlock working). Too many negatives associated with this.
None of your issues are new/unique. We have hundreds of duplicate threads and yours is yet another where the "search before posting" recommendation has been ignored.
Closing thread as duplicate, if you have further issues - please try to find an existing thread related to the specific issue: for example "removing hacktivation via redsn0w", "unlock with ultrasn0w and iPad baseband" or "o2 official unlock" and reply in the correct thread.
