Easy edge opening unknown accounts

When I use easy edge to go to facebook or yahoo it automatically opens other people's accounts. I don't know these people. I've had this phone for 2 weeks and had easy edge on my last phone with no such problem. Nobody has used my phone as the US Cellular rep suggested was the problem. It does not happen when I open yahoo or facebook from any source other than my phone a motorala. It is also disturbing that if I'm getting someone else's account and full access to it.Who is getting mine, or yours.
Anybody heard of this? Suggestions.
