So, has anyone tried putting their T-Mobile SIM into a BlackBerry 7130c yet? I know it is only a matter of time. I wrote a blog post just this morning about the possibility and already 3 people have emailed my asking me for instructions.

I am just assuming that it will work but I would love to hear if anyone can confirm that it does.

Yes, Adam at GSMPhoneSource.com is able to unlock 7130c devices.

You are right. Here is the link. http://gsmphonesource.com/reunforatcib.html

How much does a 7130c without a data plan run? GSMphonesource charges $40 to unlock over the air.

It should be several hundred dollars. My 7130e on Sprint was 479.99 outright.
