[TriLUG] iPhone 4S question

[Alan Porter]

You'll need to reference the specific model number that you have.  This
can be found in Settings / General / About.  It should start with MD.

Sprint is a CDMA carrier, and T-Mobile is a GSM carrier.  Some phones
(like the ones they sell for Verizon) are dual-standard.  Others (like
they sell for AT&T) are single standard.  If you have a CDMA-only model,
then it can not be used on T-Mobile.

Find your model number and see what its capabilities are.  This page
lists a bunch of 4S models.

I talked to sprint about it and they gave me an MSL code that they said the other carrier will need. T mobile rep is clueless about this. I stop by apple today and a rep said that the 4s will only work with AT&T, Verizon and Sprint. Any of you have an idea that can help me? If anybody wants to help me offline, my phone number is 9198836730.
