Removing MENC encryption?

[meanfishy]

I had to take my phone into the sprint tech store the other day to get my internet fixed. Instead of fixing my old phone, they replaced it with a brand new phone without telling me first.

I had encrypted my SD card and so when they replaced the phone they also performed a hard reset on the old phone.

Now I am stuck with a 2gb SD card that has some sensitive data that is not replaceable plus all my cabs are encrypted and I can not open them on the new phone

Is there anyway to remove the MENC encryption? I have tried the MS help forum and they were not any help

Thanks
