sprint self service not self anymore?

[nuuuuts]

so with this self service, do we need approval from tech support such as some code or anything like that?

i've had issues with our two phones, power off randomly, freezing a lot lately. Both phones are the stock sprint roms.

Would I be able to fill out the info and have sprint send me 2 phones? I've been to the repair stores and they take several hours to diagnose the problem, and just waiting to speak to a tech takes forever too.

thanks
