The problem with phone status i never had, but i also can't deactivate a sim. I performed a clean install and I tried to wipe cache + dalvik cache - with the same result.
I don't use FreedomPop applications, but sometimes i also have this issue ... after a reboot i see no SIM cards.
I only get my SIM cards back after i powered down the phone.
