Was hoping to upgrade my phone from the HTC desire and the sgs2 seems clearly to be the best phone on the market right now. Thing is I use my phone as my main device for surfing the net when at home on my WiFi. It's important to me that the phone operates well using WiFi. I'm hearing tho that this phone has issues with wifi connectivity, some say its minor some say its major. How are people finding WiFi on this phone?
