Hi all I have recently upgraded my HTC Desire on O2 to Android 2.2. Since then, I've intermittently been having issues going on the internet on my phone. Much of the time it's fine, but then it'll have a couple of hours of refusing any kind of data connection - it won't browse or sync Twitter/Facebook etc. I've tried rebooting, and disabling/reenabling Mobile Internet, to no avail. Does anyone have any thoughts?
