Now that would make complete sense. If you look at the size of the Thunderbolt a lot of it is due to the LTE radio. Even the Charge and Revolution (think that is the name of the LG Phone) have been said to be large because of the LTE radio size.
If they could make the LTE radio size smaller it would make huge differences in the size of the phone (depth especially).
I do not want a smaller phone... I have big hands I need a 4.3 phone...
I wasn't refering to phone size, but radio size. If you have seen the thunderbolt it's .52" thick which is almost as thick as the Droid 2 /D2g with a keyboard. The Droid X is only .4" thick.
It would also leave more room for better cooling (if the rumors are true and that was an issue), etc...
There are many advantages to having a smaller radio.
