Question Carrier limitations in USA

Hi I have been really considering getting the RAZR Maxx HD but I see only Verizon has it on lock, wondering if anyone has tried rooting it to make it usable on other carriers?

Somebody was able to modify the RAZR M's radio to work with the Verizon RAZR HD's to use 3G on AT&T and T-Mobile. See below.

I will post a HowTo for doing the required NV edit for this mod using RadioComm later tonight after work.
This method avoids the need for force loading the QV Diagnostic Port drivers by using Factory boot mode which allows RadioComm full NV read/write access.

How is this possible? I thought cdma phones were incompatible with gsm networks and vice versa?

The RAZR HD [Verizon variant] is considered a 'global phone' and can work around the world as it does have not only CDMA/LTE radios, (check it out on gsm arena as can't recall at the moment) but also GSM/3G/H+ as well. Thing is Verizon is stingy and have blocked it so it will not work in the USA without any issues, but all you have to do it change a fw settings in the radio. Funny they are as they just don't LEARN, the first time, nor the second or any other following time by just letting the phone be unlocked as sooner or later, we will get it unlocked or rooted. *sigh, Verizon*
