Hi There! Since a couple of days the internet on my Desire doesn't work anymore. (WIFI does) the weird thing is: When i have my phone in my pocket or on the table and my screen is off, it recieves gprs. But when i turn my screen on the gprs turns into 3g, then in HSPA and then it disappears. This takes about 5 seconds or less.. When i put my simcard in my old iphone 3g the internet works fine, so that means its my phone to blame and not the network Does anyone knows how to work this out?
