yeah I can change sim cards on the 920sh. I just keep old sim card inside in case it does come on, I wont relock up. It was 90usd, the hypersim media unlock is about half the price. But I also ended up spending more than 2 months b/c for some reason my friend couldnt get the it unlocked using hypersim method. He was sent the wrong hypersim by the supplier in china.
90USD
but quite worth, considering the whole process involved. and it is nice to make it internal too

Here is my understanding how it works for the media unlocking (at least until 920SH):
Items required: Active Softbank USIM, Media unlock bypass SIM
1) Activate Softbank USIM can only be obtained by registering a new phone line with Softbank Japan which requires you to have load of documents when you register. An important thing is that you need an alien card or a Japanese ID card and along with some utilities bill which proves your residential address it true and correct. This is difficult part to obtain the Softbank USIM. Unless you have a very close friend that willing to register a line for you under his/her name (which if you are using it for committing criminal crime, he/she will be the one who will suspect). Besides, need to activate roaming service if you're out of Japan.
2) The working of media unlock in 920SH will be first insert the Softbank USIM and media unlock card together into 920SH. Then when phone ask to do a repro, choose yes. The re-pro will success as it is a valid Softbank USIM and it connects back to Softbank server to do the re-pro by checking is the number in use is a valid Softbank user. In 920SH case, it extract the number from the My Contact Details part (you will see your my contact card number is a Softbank number which preprogrammed in the media unlock card. The main working point for media unlocking)
3) Switch your own SIM card with the Softbank USIM and now your 920SH will have media unlocked. This is because that although you switched the SIM card, but the My Contact Details phone number part still the same (this was because preprogrammed in media unlock card), so the phone thought there is no change in the SIM card.
923SH method is a little different as the previous 920SH method doesn't work for media unlock and I believe the solution would be changing your SIM card underlying contact card number to the Softbank one (this one is my guess).

904SH/705SH does not have media lock yet and an inactive USIM could actually play around with the functions.

True.
Depends on your seller source. The ultimately main source of course from Japan.

nice info! will update it on the first page.
actually you clear my understanding on Softbank unlock procedure too
