i am now on my knees begging like a dog, can someone anyone shed even a tiny bit of light on my problem, ive posted this in 6 forums and searched all over the internet and and still have yet to recieve a single reply. with that bit of begging over on to the issue. i have an iphone 3g (firmware 3.0), uk model locked to o2, i have done the jailbreak no problem and installed ultrasn0w, it recognises my sim and connects to the network fine, but when i try and call anyone i just get 3 beeps and the call cuts off, if i try and phone it from another mobile it says "calls to this mobile are not being connected", i have enabled caller id, still no luck, i read that it may be down to 3g being enabled so i disabled that but the problem is still there, the only other possible solution ive seen is disabling automatic time/date updates, but there isnt even an option for that on my iphone, does anyone have any idea how i can get it to actually make calls? ive tried several sim cards and even uninstalled ultrasn0w and tried purplesn0w but that didnt even take my sims. after doing a full restore to 3.0 i could manually set the time and turn auto update off, but it still didnt fix the problem. the only other odd thing ive noticed is that if i put an o2 sim card in i get a message telling me i am trying to use a "restricted network" which seems stupid as its an o2 phone, so right now its fairing better with anything but o2. i would be eternally grateful if anyone could shed even a glimmer of light on what i may need to do now for my final part, which i wish i could bet on, after my experiences on the rest of the net i can be 99% sure not a single person will reply to this thread, even if its viewed by thousands, anyone wanna run a book?
