So I finally got around to jailbreaking my iPhone 3GS last night. Everything was working great and I had a bunch of mods going on. I downloaded Boss Pref and SBPref and a bunch of themes. When I got home from work, I noticed that I was unable to connect to the internet via the ATT network but I could via WIFI. Then as I was digging around in some settings, I noticed that I had the internet tethering option available to me. AND it worked! Even though I could not browse on the phone itself, I was able to use the 3G connection and browse on my laptop. Well, I tried turning airplane mode on and off, toggle 3G on and off, removed the sim card, etc and nothing worked. So I restored the phone twice without getting my internet back. Interestingly, the tether option remained after both restores and only went away sometime after the second restore. But I still dont have ATT 3G access on the phone. Trying to browse on Edge (with 3G off) doesnt work either. I used Blackra1n to jailbreak. Any tips?
