i had an iphone and it worked with my tmobile sim card on carrier 12.0
i just bought one off ebay and it says carrier 10.0 version 4.3.3 broadband 4.10.01
will this work with my tmobile sim?
The carrier version doesn't matter. Either way the iPhone has to be Unlocked in one way or another to be used to Tmobile. The 4.10.01 Baseband can be Unlocked w/ the Gevey Ultra from ApplenBerry.com.
