I assume that trying firmware made for a GSM device, such as the 7100i and putting that on the 7130E (CDMA), won't work?

Like I said, stupid question

First, the 7100i is an iDen phone and not GSM. However, the answer is the same in that different technologies will not work with one another. GSM, CDMA, and iDen all require different base radio firmware and thus different firmware packages.

Shorter answer: No, it won't work

And the long answer? ;)

long awnser is...

GSM has 4 different frequencies (850,900,1800,1900 i believe), and CDMA and iDEN use a complete different set of frequencies. Lets say the CDMA frequency bands are called X and iDEN frequencies are called Y, and GSM are the numbers i listed. If you have a GSM phone, the software/firmware/OS on the GSM phone will only work with the 850,900,1800,1900 bands. so if you add CDMA software to a GSM phone, it wont work, becuase the X (or Y) frequency will not be supported by the GSM device.

If you know anything about remote control cars, its like how you can be messing with 2 cars with RF, and the MHz is different, so you can control both at the same time. and they wont get mixed up. HOWEVER every once and awhile you get a remote that can control 2 cars (which would be the GSM devices, becuase 4 frequencies).

another solution, if you know anything about HTML, C++ or any computer language, its like trying to program a program in pure HTML :-p

any help??

The long answer is it simply will not load. Forget about frequencies, radio technologies and the whatnot - RIM has built in controls to ensure that you CAN NOT load, for example, 7100 code (which will work on any GSM 7100) onto a 7130 or an 8700 or a 7250. It simply can not be done.

People have invested (WASTED) a lot of time tryin to get v4.1 for Model A to work on Model B. Not happening.

I was joking, was not asking for the long answer, if the answer was no, then the reason was irrelevant... I guess humor does not come across well on the net..
