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 Joe’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)
