As soon as I switch on my Nexus 4 there is this pop up saying "R world, requesting handset configuration" and the moment you click OK my network connectivity goes kaput completely and the only way to restore is to restart my phone again and then cancel that popup...its strange and frustrating...why is this happening? any solution?

GSM phones in India can be hacked Mobile phones on the GSM network in India are not very secure, according to a demonstration by security company, Matrix Shell. Business Line reports that the four founding members of Matrix Shell claim that they were able to hack into GSM phones and use the International Mobile Subscriber Identity, which is a unique number assigned to the SIM card. They were able to make phone calls, intercept phone calls, inflate the bill of a postpaid subscriber and deplete the balance of a prepaid subscriber. Service providers will not raise a security concern from any of these activities, because they appear as though they were made by the person whose account it is. They used firmware called Osmocom, and using software they wrote on it, they were able to hack into a GSM phone. They explained their ease of hacking into a GSM phone here with the level of encryption Indian GSM networks use. Akib Sayyed, one of the founders of Matrix Shell explained that standard encryption on a GSM network should be 5/1, but in India, most providers use 5/0, which essentially is no encryption. He did not specify, however, which Indian networks in particular provide the lower encryption. Operators tend to avoid heavier encryption as this would mean the time taken to connect the mobile to the Base Transceiver Station would be greater. Networks want to avoid that as there is a lot of traffic on the GSM networks. More encryption would also mean more hardware upgrades. Those using the correct encryption frequently shut it off.

I am facing a really strange problem in iPhone 4 CDMA. Inspite of various efforts by me & Gaurav, we are unable to understand the source of this problem. Request Gurus to please enlighten. Details are given below:- On getting the phone from Gaurav I asked web world to transfer my number and after dialling *228 it started working for calls & sms. However, after 2 days i noticed that its not making or receiving calls. On dialing any number it instantly says disconnected and incoming callers hear "phone is switched off" message. It starts working after 4-5 hours or a day. Then it stops again after 2-3 days. Signal bar is full and its NOT an AKEY issue as even after entering the correct akey it doesn't start working. And even if i don't enter akey it will start working on its own after some time. Gaurav even changed the ROM to stock ROM (from earlier Chinese ROM) as suggested by Genius but the problem reappeared after 2 days. Its on iOS Version: 4.2.8 (8E401). Phone shows the following: PRL: 212 ERI: 5 MDN: 000 000 4660 Gaurav knows about the baseband etc issues and has ensured that baseband is not upgraded changing the ROM. Since it works sometimes, so we think it shouldn't be a MIN, PRL or Network related issue other wise it wouldn't work at all. It doesn't seem to be a hardware problem as phone's new & hw issue would probably be permanent or at least degrading quickly to a permanent problem. Couldn't find any one with similar problem on the internet even (except this 1 topic - but it doesn't have much details) Which leaves us with no other suspect for this problem. I am at my wits end waith this thing. Any advice resulting in fixing this will have a Sixpack of Kingfisher (or your favourite brand) being delivered to your doorstep. If you need to know any other technical details then either me or Gaurav will post it here. I think I have included everything.
