Whenever I start to use my GPS (not just switching it on but actually use it) for instance using google maps and navigation, it seems to kill my 3G connection. I can still see the icon for connection however but it stalls completely. I have to switch GPS off, then force wi-fi on, then switch wi-fi off again to establish 3G connection again. This means that I can't use my GPS at all whenever I'm off wi-fi and want to use 3G. This is absolutely not OK. I've just started with this Android business, choosing this over iPhone. Please help me not to regret my choice. Any Ideas? I'm on an unbranded and unlocked desire.
