It seems a bit obvious,. but have you tried T-Mobile themselves? They might do it for a fee.

 

They says this on their site:

 

Have you put another network's SIM card into a T-Mobile phone?

You'll need a subsidy PIN to unlock the phone. To obtain a subsidy PIN, or if you've entered an incorrect subsidy PIN, please call us on 0845 412 5000.

 

Apparently they charge £15.

Hi. Restore the software to 4.2.1 then jailbkreak it by going on Safari from your phone and go on www.jailbreakme.com and swipe it to jailbreak the phone. Then order a sim from giffgaff or one that some members post up so you can order it from them directly and its cut for you.

A suggested above, T-mobile might do it - not sure if they can while it's jailbroken though. Call them. Maybe there's a Cydia app or something? I wouldn't know, I don't jailbreak Smiley Wink

I think it is safest to get your old provider to unlock it, even if it costs more.

If there was any problem unlocking because of it being jailbroken then the trick would be to plug it back into iTunes and get it updated and unjailbroken, get T-Mobile to unlock it, then jailbreak again.

Re: How to unlock my iphone 4 on a T-mobile network to use with giff gaff

JailbreakMe via Safari only works on iOS 4.0.1 or below I'm afraid. Plus you need shsh blobs saved to downgrade iOS. Best mentioned advise is as above, to approach Tmobile, who can carry out an official unlock. This won't void you warranty either Smiley Happy
