I am curious about whether anyone with a Nokia Lumia running Windows Phone 8 have upgraded to 8.1 using the Developer Preview.
I am aware that going to 8.1 with the Developer Preview will void the phone's warranty - but mine already expired. My concern is that updating to 8.1 with the Dev Preview will make the phone inoperable on VZW. Any info is appreciated.
Yes, I have updated two Lumia 822's and both are working fine on Verizon Wireless. As far as the warranty, the disclaimer only says that it "may" void your warranty. So far, no know cases have been reported as far as I know. It's well worth the effort to upgrade but the regular update should be coming out within the next couple months. We have already received three updates to 8.1 itself.
