If You had the random reboot problem the recent update will fix this it will also get rid of the Free Hot-Spot as well. As for problems I have had the new update for over 2 weeks now and my phone runs better then ever. I had the reboot problem but it was not as bad as soem have repoted (I got 2 or 3 reboots a day some times none)
As for tuning down the update all you can realy do is keep it up eventualy the phone will stop trying to update. I had the original Droid when it first came out and had opted to drop my phone down to a normal flip phone for a short time to save some $$ 4 months later when I re activated my droid i had missed the Froyo Update and when i tried to manuely push it to my phone the phoen told me ther was no update. I called CS and they told me I missed the window to get the update and woudl have to wait untillo the next Update to receve both the original Froyo update and the new one that was coming out soon. As it turned out about a month latter I got the update and it installed the first update to my phone and then the secoudn update (Wich was a pain because I had to go threw the process twice)
Basicaly if you avoid the update long enuf it will eventualy go away but if you want GB when it comes out you will have to acept the update then.
Id advise just geting it the last thing you want is to not get it and then have it cause a problem for you with the GB update down the line....
