I get the same thing after doing the last update to JH7. . .(I got the JH7 OTA) now every time I check for an update I get the same thing you do. "unable to connect to AT&T server" or some thing close to that. . .
Ive called AT&T, they pretty much know nothing. One guy said he reset the registration on my sim card, checked my IEMI number, blah blah blah. he said "try again in 24 hours, I'm positive that will fix it". . .. if not then its a Samsung problem not ours
No luck. Its not a huge deal at the moment, but when I see that 2.2 is out, I'll feel like I'm being robbed until I can get it fixed. .
I dont really want to do a complete restore on the phone, because I feel like it took me a month to get it just the way I like it. .And I dont even know if that will get it back to being able to get updates. . . .
Thanks Maxwell. . .saw your post after I replied to the OP . . . .Ill keep that download and see if I can get it figured out for future updates.
