I used redsn0w_win_0.9.6rc16 to jailbreak my iPhone 3g, loading Cydia 1.1.6. i. iOS version 4.2.1 (8C148) ii. MODEM FIRMWARE BASEBAND; 05.15.04 iii. iPhone 3g iv. Jailbroke with redsn0w_win_0.9.6rc16 – using iPhone1,2_4.2.1_8C148_Restore.ipsw 1. Then I “thought” at the time the way to Unlock was to load SAM (Subsciber Artificial Module), and follow directions there? 2. And here is where my confusion started because I ‘thought’ 0.9.6rc16 to be the most current version, yet I find a bunch more versions… a. redsn0w_win_0.9.10b1 b. redsn0w_win_0.9.14b1 c. redsn0w_win_9.6rc19 I think my critical question is: Is there a version of redsnOw that not only Jailbrakes my OS, but ALSO, UNLOCKS THE CARRIOR? And, is it safe to go back and repeat a jailbrake?
