my phone was shipped with 0.15 and i think thats why i've been having the wifi issues. (rebooting nonstop anytime i connect to wifi)
There has been at least 1 update but I think it went out before the phone launched. I picked up my phone on launch day with a 0.16 base band. Another user on this forum reported getting an OTA to the latest (current) build of 1.53.531.16 which I assume also updated the base band to 0.16
You could try a manual check in by dialing *#*#2342546#*#* in case your wondering 242546 spells "checkin"
Unfortunately i'm not on the stock ROM anymore so that isn't an option.
After doing a bit of research, it seems like the only way to get the baseband update would be for me to somehow revert to the prerelease TMO ROM, then wait for the OTA that was sent out to the prerelease devices which has the baseband update included.
Which is basically impossible, because no one is going to be running that prerelease ROM right now.
So i'm basically clueless at this point. probably just going to see if i can warranty swap it through HTC and hope they don't care about the bootloader being tampered.
Any input from anyone is definitely appreciated!
Your in luck! Someone has provided you with a method to do this.
