I have discovered something interesting about UMA.
I have a couple of cordless phones, if one of them is in use, my UMA connection drops back to EDGE.
Cordless phones use the same 2.4 GHz radio frequency as Wifi.
Unfortunatly, they do not show up in a Site Survey. This would explain a lot of the intermittent connection issues, particularly when you are using it in an apartment building.
Don't know it this applies to your situation, but it does explain a lot of the strange behaviour reported with UMA.
and no, i was out in front of starbucks....no apartments nearby.
wasn't on UMA either.
i get dropped from EDGE to edge and loose mobile net and BIS
What kind of sites do you go on? What happens when you go to mobile, simple sites, such as google? Try disabling your javascript in the browser settings.
Found the problem,I cleared all the content cache,pushed content,cookie cache and went into security options and cleaned the memory,backed up perfectly..
