the camera software does not have the capability to roll back your current software which is likely .04, .05 or .06 back to .02 which is what the camera was made to work on. the software was never intended to be released and was leaked and will not be supported by nextel...altho it would be very nice to have a camera working for any software version. as far as messing it up....i would assume that it would, but it would more than likely stop you before you got too far because your software is supposed to be below .02 before you start! if you have NSP, give it a whirl!
