the Omnia is confused...there should be only 1 MyStorage folder in your Omnia (in this case you have \MyStorage and MyStorage2 folder) what you can do now is to delete or move away one of the folder and then do a soft reset...it should solved your problem...
This "MyStorage2" thingy is a bug. I had it several times. I deleted original "MyStorage" and renamed "MyStorage2" to "MyStorage".
Have to soft reset and it works alright.
But why buy a $1000 phone and continue to have problem. That's why I decided not to accept my phone back from Service Centre.
