Hello All, I currently have a 1st generation iPhone, not jailbroken, on AT&T. I love it. Sadly, I spend about 20 hours a day encased in metal buildings which block the cellular telephone signal. These buildings have excellent Wifi, which I am always connected to. Now, how can I make my iPhone ring when somebody wants to call me? My ideas: 1. [Near ideal, if possible] An iPhone Skype client that runs continuously in the background and/or receives push notifications I don't care about battery life, I want a phone that rings when someone calls it, whether it is in my pocket or I am fiddling with my Calendar app or whatever. Make my phone ring, please, for the love of god! 2. [Acceptable, if possible] iPhone VoIP client that can only receive calls while in the foreground. (Google Voice client would be ideal, Skype client acceptable) This is an acceptable compromise if there is absolutely no way to make my iPhone ring if the client isn't in the foreground. In this case, someone can send me an email saying "open your Skype app", then I will open it, then they will call me and it (iPhone) will ring. Or I can "place call" in Google Voice and then open my iPhone Skype app and then my iPhone will ring, I will pick up, and I will hear the dialed number ringing. Success. 3. [Ideal, probably impossible] Google Voice client continuously running on iPhone This would involve a hypothetical "Google Voice client" that installs on the iPhone (perhaps it needs to be a jailbroken iPhone), and then runs continuously in the background or alternately receives push notifications when I receive a call, so it can ring even from the background. When my Google Voice number receives a call, it will ring my telephone (AT&T, when I have signal) and it will simultaneously ring my VoIP phone (maybe Skype, when I have Wifi but no AT&T). When I call out, it will seemlessly use VoIP from Skype or AT&T depending on Wifi and cell signal availability. Maybe it would even seemlessly transition from one to the other? I am dreaming now. 4. [Not good enough] The 3G Microcell thingy It looks like this would work perfectly, but it is too expensive and I would only have it in one location (say, my bedroom or my lab). I want my phone to work in any of the many metal-encased-Wifi-enabled rooms that I frequently occupy. Does anybody have any other ideas? I am willing to Jailbreak my iPhone, but would prefer not to. I currently have a 1st gen iPhone, but I would like to buy a 3GS, would that influence any of these solutions, or the ease of Jailbreaking? Thanks.
