Hi, I have an iPhone 3gs and want to upgrade it to iOS 6.1. I do not have the original SIM so it needs to be hacktivated and carrier unlocked. Serial No:- 86944xxxxxx (Manufacturing Date 44th week of 2009) Baseband:- 05.12.01 Please let me know the best possible solution to hacktivated, jailbreak and unlock my iPhone while preserving its baseband. Appreciate your help. |
Use the snowbreeze 2.9.9 jailbreak, it works with 6.1 as well now plus it allows you to create a modified firmware which does not update the baseband as well. This jailbreak is backwards compatible until iPhone 3GS (it works with all iPhones that had the A4 chip). If you preserved your baseband you can install ultrasn0w afterwards (cydia) in order to bypass the simlock/carrier lock. |
