I've had an iPhone 3GS for a while now just for use as my travel phone. Unlocked, jailbroken, running 4.1.4 or something ancient. Today I got fed up with the out of dateness of it (I only use it a couple weeks a year, so generally I just leave well enough alone) and decided to update with the new JB update to 5.1.1. THEN I realized that I only really care about unlocking the phone, not so much about JBing. Though I do like the MyWi, really I need to be able to put a foreign SIM card. Now, I've backed up my blobs or whatever through Cydia, and I now have my phone with 5.1.1 and Cydia on it. I checked and my baseband is 05.16.05. Can anyone tell me if I've just ruined my iPhone for what I use it for? And if not, what's my next step? How do I unlock it from here? Hope I didn't ruin my phone! Thanks!
