Same Here. Exactly the same issue as Quoted above: Sometimes when unlocking the phone I will Unlock and it will hang for about 2 seconds then it will soft restart to the Loading Screen animation. From here I can unlock the phone. Sometimes it will not connect to 3g again, but if I Toggle off/on my airplane widget it works. I've learned to live with it as it only happens occasionally, but if there is a Fix I wouldnt mind resolving it. it tends to happen at least once a day.
Actually I am Using .75, only Just got this phone about a month ago and Put the Rom on. But I just looked it is using .75
I think I know whats causing the reboot (was actually pointed in the right direction by a problem r2doesinc was having with OM(F)GB roms) but not sure how to actually fix it. Also not sure why it would affect data/service on the reboot though. I simply dont have the time or will to put into trying to fix it when most have moved on to GB based roms. I will fix it when I start working on GB Angel but I'm done with froyo.
Makes sense, Cant wait to see GB Angel
