I bought used 3GS, found Cydia and Ultrasn0w already installed, 5.0.1, modem 06.15.00
I'm an iPhone newbie, though I'm a computer hardware designer and utility programmer. I'm learning iPhone stuff like crazy, but have a LONG way to go. By now I probably know just enough to be dangerous.
As the title says, I bought a used 32GB iPhone 3GS, without a SIM card. In the seller's ad, there was no mention of its being jailbroken or unlocked. But leafing thru it, I found Cydia and Ultrasn0w already installed. Does that mean it's already jailbroken? How about unlocked?
Serial No. 88928xxxxxx
Carrier 11.0 (Is that AT&T?)
My intention when buying it, was to jailbreak it to get it to accept non-iTunes apps, and then unlock it to use it on my old carrier T-Mobile.
I have heard that there may be some difficulty unlocking this combination of 3GS, 5.0.1, and 06.15.00, and this serial number with 3rd, 4th, and 5th digits "928". Is this true?
Also noticed that, when I tapped the already-installed Ultrasn0w while connected to my house's WiFi last night, Ultrasn0w showed me a message like, "There are conflicts between resources" or something like that. Sorry I didn't write it down. And now I'm not on WiFi, so can't get it back again. Maybe tonight.
I'm starting to wonder if the previous owner jailbroke this thing, then loaded Cydia and Ultrasn0w, and tried to unlock it, only to run into problems.
My questions are:
1.) Is this phone already jailbroken?
2.) Is it unlocked?
3.) If not unlocked, is it possible to unlock it? Or does this combination of numbers, prevent that?
4.) Do I need to un-jailbreak it, and re-jailbreak in some special way, to make it unlockable?
