Thank you so much for letting me know this can be done! I spent a fruitless hour with HTC (again!) today with the CSR yelling at me and telling me it was impossible to go back to Gingerbread because my phone would no longer be compatible with something called "radios" now that I've (unwittingly, unhappily and pretty much nonconsentually) accepting the ICS downgrade. Please, can you tell me how I can revert back to Gingerbread (which I was totally happy with and that worked perfectly) on my phone, which is an HTC Evo 3D? My phone is completely worthless for anything, even after trying to apply all of HTC's and Sprint's suggested fixes. Most of those fixes either did nothing (best case) or made things worse while not fixing anything. The only other suggestions they have entail me incurring more monetary expenses and/or being without my phone (which I pretty much am anyway now) for weeks. I'd really appreciate any help you can give me!
