  1. REWARD for unlock baseband 3.10.01 on Iphone 4 100 EURO

  2. 100 euro is nothing. i think they getting more for not to release unlock. Think, why is so big prices for same strange gevey or rebel sim card's?

  3. 100 euro just from me :) , think again from hundred people ..or maybe thousand that waiting for unlock on the lates basebands , anyway this is the las time when I buy an Iphone , to much problems , on HTC , Nexus , and other phones with Android everything is FREE.
    PS: personaly I give 200 EURO just to unlock'it and sell'it , because without unlock is worthless , thank you dev team, thank you GeoHot , than you all for this ...but with this latest basebands is to much

  4. Android is like the Windows PC Platform in Mobile World,
    so Jump in & forget about that little apple Device.

  5. belive me it's last time on apple devices , even if I want to pay on AT&T 200 300 500 1000 USD 2000 USD :) they cannot unlock your iphone 4, soon or later it will come an unlock for latest baseband just because is all about marketing ...but not for me , I wont buy another iphone:
    PS: why dev team or GeoHot make an application to unlock device's everytime you pay 100 200 300 500 USD , it doesn't matter how much it costs , just make for those who wanna pay for it :(((((, so You have a phone and want to pay money to unlock'it ..and you can't :)))
