Reviewed by a customer on Facebook group after we replaced his iPhone 3GS baseband chip (6.15.00) via mail-in service from Italy.


Very pleased with Richard’s service. We communicated extensively… enough so that I felt I was starting to be a bother, but he was always courteous and forthcoming. The service I used was the one where he replaces the chip that had the iPad baseband on it, for my 3GS, with one that has an earlier, unlockable baseband. The phone was returned to me working perfectly, and this baseband downgrade allows my GPS to work, which was broken with the iPad 6.15 bb in place. All my data and apps were still in placed, too. Just turned it on, and started using it, when it came back. Bravo! — Michael H, US-based client (via mail-in service)


“Extremely professional, perfect service!” — Alain D, French expat in Tamil Nadu, India (via mail-in service)


“Beijing iPhone Repair fixed my ongoing problem with the baseband. I wasn’t able to make any calls or to connect via WiFi, now it’s working again. Thanks!” — Philip H, German expat in Shanghai, China


“Thank you for your work and for your support. I was a bit worried at the beginning, but as you said I have an unlocked baseband and the GPS works perfectly. Your work worth every cent!” — Miguel A, Australian-based client (via mail-in service)


“I just received the board and installed, my iPhone 3GS is up and running again! Thank you very much for your service.” — Tony K, US-based client (via mail-in service)

Shouldn’t you be using your iPhone instead of just waiting for the ultrasn0w unlock (that will never come)? The solution is right here, right now.

  8. Hi.

    I have a 8gb 3gs manufactured on week 52 of 2011.

    Tried to jailbreak and unlock it using ipsw from snowbreeze, but not successful. I think i fried the baseband as it does not turn on normally now and when it does, it displays no wifi, bluetooth etc. And it keeps on rebooting.

    Could you replace my baseband? Or do you have any idea on how to fix it? Thanks in advance.
