I recently went into a t-mobile store to ask for a blank or deactivated t-mobile sim. I wanted it to do the t-mobile sim swap trick for getting MMS to work on the iphone 5. The 2 unfriendly t-mobile employees just stared at me blankly and I then I asked if I could just buy a blank t-mobile sim. They said no. They wanted so badly to deny me of what I wanted. So I eventually get it out of them that they can sell me a $10 t-mobile prepaid sim that comes with 5 days of service. So I bought the sim and they set me up with a new phone number and everything. I get home and pop the sim in and I was playing around with settings and I noticed that the default hotspot password was "fibber0445" - quite an odd default password if you ask me. Is that something that these 2 employees could have set up on my sim card while I was making the purchase? I was thinking that by "fibber" they were implying that I was lying to them about something.
