Hi,
My problem is simple.. I'm a knuckle head. My husband gave me a 3G Iphone for our anniversary, originally locked to O2. He got it unlocked and jailbroken in Pakistan to use with my local sim and gave specific orders not to update or anything. I did use the phone for a short while and then like a big dodo updated it through itunes to 2.2.1 with baseband 2.30.
I got advice on this site that I can use piggyback sim to use the phone. However, I still have some unsolved questions.
1. After updating my phone got locked and Itunes said something like 'Invalid Sim. Insert original sim or ask carrier to send replacement sim'. The Iphone shows the same message plus the Emergency Call screen. I can slide to unlock to make only Emergency call. What does this mean?
2. I had an O2 sim, I tried that with my phone but still the same. I guess the sim has expired. Should i try it while connected to Itunes or just putting the sim in and switching on will work?
3. If I use a piggyback sim, should i just insert it and turn on phone for it to work? Or should i connect phone to Itunes and then turn it on with the piggyback sim in?
I would be really grateful for answers. I'm very confused and it breaks my heart each time I look at my Iphone sitting pretty in its case!
