Hi all, just recently I bought myself an iPhone 3gs. It had iOS 4.3.5, but I downgraded to 4.1 and jailbroke it. Everything works just fine (wifi, youtube etc...). Except there is no GPS. I tried many ways, searched this forum, but nothing helped me. I have iGo, TomTom, CoPilot navigations. All of these apps can't find GPS signal, even in open space it still says Poor GPS reception. I have jaibroke my 3gs with Limera1n. Didn't install iPad baseband. Here's some more info: Version: 4.1 Model: MC132KN Modem Firmware: 05.16.02 Bootloader: 6.4_M3S2 Any advices would be appreciated Thanks Update 2011/08/26: Just installed the newest TomTom Europe version. Now it locates me very well. I went for a ride in city, it navigates, but it delays. What could be the problem of that?
