all comes in JPN Firmware if bring in from Japan. If Hong Kong/Taiwan set then comes with their own HK/TW firmware.

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.

90USD
but quite worth, considering the whole process involved. and it is nice to make it internal too

i think snowLeopard is having a problem to fully understand in English (or is he/she using translator to read our posts as well?)

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

Whoa .. so many procedures. Thanks for clearing things up
BTW: Not all phones requires media unlock right ?

BTW, vodafone, you have my PM on docomo PRIME series SH-03A.. Reply me ASAP..~ keke..

models 904sh/705sh and older arent locked with media, 706p 705p, toshibas unlocked, and 920sc dont have media locks

true also . no wonder the english appears weird. he was using a translator...

quick question. the CPR thing, i know it varies between models, telco, and sim type used. can you guys give me a worst case scenario?
cpr once a day/week/fortnight etc?

still, it depends. if you are in signal blind spots where even hard for normal phone to get signals, then you might be busy doing CPR to your phone.

but normally CPR occur once or twice a week. if you manage to get GSM signal, you might only CPR once for a few weeks

Guys, I'm back

Yeah, but its still depends on your hypersim
My banana phone almost 1 month no need CPR at all
Even I take KTM/LRT, drive into basement car park or enter lift
Now I enjoy the banana phone with new earphone adapter + Creative earphone + backup battery

sounds like you totally fall in love with it
you manage to get GSM signal? 1 month din't do CPR...solid weh

cool, once a week is bearable i suppose.
what do you guys mean gsm signal? aint all signals are gsm? or u meant differ from 3g signal?

i'm into the slides woot.

oh and like the cpr occurs only when your signal drops out and unable to regain right? not like out of the blue thing.

most likely you will get GPRS signal(known as 2.5G if i am not mistaken) if you are using GPRS or 3G phones, eg k810i, N73 etc.
chances to get GSM signal(known as 2G) is higher if you do CPR using GSM phones, like Nokia 3310, 8250 etc.

CPR when the signal bar there shows "圈外". if "UIM not recognized" or signal bar there shows "TML", you just reboot the phone, then you are good to go.

okay you lost me there a little.
from my reading of this thread i thought CPR = when signal bar = "圈外" = put the sim card into another phone and manually search for signal, then insert back into docomo? not just plain rebooting right?

i get the gsm part now thanks. gsm = 2g , gprs = 2.5g , 3g = 3g , 3.5g = fake wm device stuff lolololol.

woot i have a 6510 here i suppose its gsm. otoh, i doubt 3g video calls will work given that its running gsm signal?

any ideas where I can buy the Sharp903 in malaysia?

how much is it now?

TQ TQ

"圈外"-->CPR
"UIM not recognized" or signal bar there shows "TML"--> reboot the phone

definitely can't work for video call if you set it under GSM/GPRS mode

around RM700 or so for second hand set, depends on the phone condition.
look in the Garage sales section

you can save more to get better models..~

oh crap, i think i stuffed up. in aussie i'm using Three which is 3g only USIM. this would mean if i use docomo phones it will be very unstable?

in my experience, while i set my Docomo phone to 3G mode, i was not able to receive calls.
CPR occured quite often as well due to 3G coverage here is not as good as other developed countries.

Yeah
GSM signal all day long

Surprise~
