Took about 2 and a half days to complete from start to the end. The cost was maybe a little high but still cheaper than some sites and they have a good turn around time. I've used them in the past for unlocking BB's and they are flawless.
Didn't have alternate network SIM so did an iCloud backup and factory reset. Bought new SIM and there you go, the phone is up and running.
They are good.
