Me too cursed with 'No service'
I also am using(trying to use, actually) the Iphone here in India. Am on 1.1.1. I want it to work with Airtel but am, like so many now, cursed with 'No service'
Have virginised and re-unlocked like 5 times or more , but the phone works fine for about a day or so and then goes back into 'no service'.:(
So this is some of what I have done so far,
1. FYI, i used jailbreakme.com to activate and jailbreak the phone, and then installed anysim from iphone.blurgle.ca/repo source. The first time I started getting it, I just restored the phone(just restored it, did not virginize it) and it started working, worked for a day or so and went back into 'No service'
2. Next time, I restored but it didn't help, so I virginized it using 'i.unlock.no' virginizer and restored it and again went through the entire process of jailbreaking(used jailbreakme.com), activation and unlock(anysim 1.1 from i.unlock.no), this time i read in some forum which instucted to manually upload the lockdownd file to get it to work, did that, didn't quite get the logic of it as jailbreakme already activates the phone, it again worked for a few hours and then relapsed.
By this time I had read in forums that people thought that maybe it was a heat issue or excessive wifi use that caused the problem(my phone too does get pretty warm when i use the wifi for long hours) so this is what i did the third time, :)
3. Again virginsed-->restored-->blah, blah, blah-> unlocked. But this time after unlocking i did not sync it to Itunes, did not use wifi(so no songs and no internet on iphone, u can imagine, owning an iphone but no internet and no music), this time again the phone worked well almost for 2 days and then was back to 'No service'
4. So yesterday night, after all the above mentioned dilemma, i again set back to do something, but this time instead of going through the entire virginize->restore->jailbreak->activate->unlock routine, i used onesim to undo anysim and then again anysimed it(kept the AT & T sim in the sim tray during both one sim and anysim, don't ask why, had read again on some forum, didn't quite get the logic again, but did it anyways). This time after it finished with all the processes, i put in a sim from BSNL(another cellular operator in India), it didn't work.
Frustrated, I put the phone in airplane mode and let it charge, after about 4-5 hours, i turned off the airplane mode and phone went into searching mode and came back with full signals(with the bsnl sim).
Again, I had read in forums that some people thought that the phone went into 'no service' when the phone's battery levels fell below some level, So yesterday after my phone started showing full signal and as the battery was fully charged, I decided to drain my battery, so I turned on wifi, bluetooth, installed ssh and kept it'on' too(as it is known to be a battery drainer), installed a whole lot of apps, let battery drain to 10% but the phone showed full signal during the entire test drive;) .
So finally after all this, kept the phone on charging and went to sleep, used the phone today the whole day without any problems(with the bsnl sim) and in the evening just decided to put in the Airtel sim in the evening, as soon as i put it in the phone went back into searching and came back with 'no service':mad:
and has been on this dreaded message ever since,
So anybody, please suggest any more solutions that i can try out,
anyways, i'd like some people who have the patience to let go of thier iphones for a few hours, to put it in airplane mode and let it charge for few hours and then switch off the airplane mode, does this get your network back?
