Dropping calls after 1.1.3 upgrade

[audiomixer]

How can I find out if my iPhone is a 1.1.1 OTB? I'd like to downgrade and upgrade to 1.1.2 again as well until 1.1.4 comes out. Or can you link me to the place that teaches you how to downgrade? I'd appreciate it. As for restoring your iPhone, it helps it out a little bit. Mine has reduced the amount of dropped calls. It will make it a little better but it doesn't solve the problem completely.

A couple of places. http://www.hackthatphone.com/113/iphone_downgrade_113.html
and http://i.unlock.no should do you fine.
http://www.intoiphone.com/ should help you ID the bootloader version.
The whole process only took me four hours since I screwed up 4 times yet I was able to recover each time. I used a macbook and itunes 7.6 to do it all.
Good luck.

I have an original iPhone (OOTB 1.0.0) and 1.1.3 is driving me crazy. So if I follow those steps and downgrade the baseband to 1.1.1 and then oktoprep back to 1.1.2 I should be ok? Will modifying the baseband like this "break" my iPhone? What I mean is will doing this effectively do the same things to the baseband as unlocking does?

I'd like to do this for the time being until 1.1.4 or another firmware version comes out that hopefully fixes this problem. But I don't want to unless I can easily just hit "restore and update" from iTunes when 1.1.4 does come out and not run into any bricking issues.

Just jumping aboard this train... I know one thing from my experience: my iPhone doesn't handle cell tower hand-offs worth a **** since updating to 1.1.3 (it is jailbroken, on AT&T). I traveled by car over the weekend, and I couldn't hold any calls longer than a minute or so (going about 80 mph on the interstate). Also, last week at home, I was using my Plantronics 520 Voyager headset; before a call, I had full bars, but when I placed a call, I noticed the signal meter dropped all the way down to 1 bar for the duration of the call. Person I was speaking to said I was cutting in & out; again, I was stationary, sitting at home. Funny thing is, about 1 minute after I terminated the call, signal meter popped back up to full bars....

Tell me about it...Apple can't even meet the scheduled release date of the new update that's suppose to come with the new SDK and hopefully get rid of the "dropped call" problem we've all been experiencing.

So I was able to downgrade successfully using these steps:

I have the 3.9 bootloader so it was relatively painless. I ran into some hiccups though which freaked me out a bit:

1) When I first loaded up Independence it wouldn't break out of recovery mode. I had to restore with 1.1.1 again before it would
2) Downgrading to 1.1.1 was fine. The baseband downgrade from 1.1.3 to 1.1.1 also worked fine
3) During the whole process I got a bunch of Invalid SIM errors. I just ignored those
4) After doing the baseband downgrade I still couldn't use the phone part even though my baseband and firmware were in sync. I had to do another 1.1.1 restore for my phone to start working again.
5) Unfortunately I couldn't restore from my backup (the same one I've been using since 1.0.0) so I had to create a new profile. Bye bye text messages and notes and all my user preferences

I'm gonna stick with 1.1.1 for now. 1.1.2 is useless and I don't feel like doing the extra step to get up there. I'll just jailbreak it to fix the TIFF exploit and leave it as is w/o installing apps. It was installing apps in the first place that got my phone unstable and why I upgraded to 1.1.3

1.1.4 is out. Have any of you with this problem upgraded yet? I kind of don't want to now that I went through all the trouble of downgrading to 1.1.1. Figures Apple releases an update the day after I downgrade -_-.

1.1.4

I've just installed 1.1.4 and so far so good. It seems to have fixed the dropped call problem from 1.1.3 for me.

I'll have to second this reply. So far so good over here. Very happy! I hope it's the same when the SDK update comes out.
