For those who got the Fly SLT100 from The Link, I have just been emailed by the company I always used to get phones unlocked and they confirm that they can unlock the Fly SLT100.
I have tried to get my Fly SL600 unlocked locally, but as I use it on vodafone I do not need it unlocked, but all local shops just look at it and shake their heads.
Anyway mobyrepairs.com in Telford can unlock this by a postal service.
I have used them many times. They also offer their services via ebay. I have never had a problem with them and every phone comes back fully unlocked.
send your phone to them by recorded delivery, then they send it back on generally a same day service by recorded delivery.
So they charge £7 including return postage and you then pay the £3 or so to get the phone to them.
If you need any other info PM me.
