I supprisingly found that some turboSIM similiar card stickers only sold $20~30 (around 200 Chinese yen) in the domestic online store. Accroding to testers incasually some Chinese Iphone Forum, those 'cheap chips' work perfectly.
those tester's iphone acutally came from different countries in North America or Europe. Besides some of those card stickers are domestic manufacture, some are made by a foreign team called Gevey.
When handred-buck stealthSIM and TurboSIM spread all over the ebey, It is really suprising to see such cheap alternitives hiding there. I've already decided to unlocked one OTB 1.1.2 iphone by the 'cheap chip'.
I think it's a really good news for whom can't wait till software unlocked approach released but unwill pay that much for the TurboSIM. Go and find a Chinese guys for help
Here's one link to the Card sticker I used, but all in Chinese.
