I just bought an unlocked Lumia 620 to replace my 640. I wanted the smaller phone, a throwback to my old HTC Pro 7, which fit my hands and pockets so nicely. I'm on AT&T, so it's working like a charm, although I never really will get over connecting to E or H for cellular data instead of 3G or 4G. So far, I like the phone. But I had some trouble at the start, and a reset with the Windows Device Recovery Tool fixed it all. But I tried upgrading to 10 with the developer preview, and I lost my data connection, and it would constantly drop my cellular signal so I couldn't do anything with it but wifi. No calls, no text, no data. The guy at AT&T couldn't figure it out. I couldn't figure it out. So I flashed back to 8.1 again, and I suppose if I have to, I can stay at 8.1 until the official 10 is released for my phone. But, I don't like to give up until all my resources are exhausted, so here I am, making an account and posting my first post here with a few questions.
1: Any idea what would cause me to lose all cellular signals when I update to 10 with my 620?
2: If I can't upgrade to 10 and I have to wait for 10 to be released officially, will the fact that my phone seems to be branded Vodafone delay my update?
3: If the Vodafone branding will delay my 10 upgrade, can I debrand/unbrand the phone?
