If i have incriminating information from my spouses phone, where do I send that information for evidence of infidelity?

The answer depends entirely on how you obtained the information.  Generally, you should give the information to your attorney to use in your case.  If, however, that information was obtained illegally (e.g. you broke into his phone), no lawyer should want to touch it.  If it's the latter, you might also consider how you might use what you have to obtain information legally that might be used at trial.
