How to determine real or pre 2.0 firmware?

I did the Thursday "illicit" 2.0 firmware. Ended up with some crashing problems to where my phone wouldn't boot. Went into restore mode today (Friday) and iTunes successfully downloaded and installed firmware. When I look at the "About" page, it shows the "5A347" build that was the same between the Thursday and Friday. Any well to tell if its the Friday official iTunes 2.0 firmware or the illicit 2.0 firmware?

Easy. If you got from iTunes and not some link off a website, its real.

True for a normal scenario, but mine was locked up and had to be put into the firmware restore mode. I'm not sure if iTunes did a restore with the real or Thursday version. Attempts to do the restore on Thursday failed so my hunch is I have the official fw now... Just can't verify it because the reported version on the iPhone doesn't include the extra identifiers described in the original MacRumors post. Anyway - apps are great but the sync is painfully slow.

Have another issue that I think is coincidental timing...looks like my phone always thinks headphones are plugged in regardless of the visible reality. I Guess whatever the switch mechanism is in the jack is toast. Don't think its related to the firmware.

******************** MacRumors firmware post **************

The official iPhone 2.0 Firmware is now available through iTunes 7.7. The new upgrade file carries the same build number (5A347) as yesterday's early leak:

iPhone1,1_2.0_5A347_Restore.ipsw

The "1,1" designation is different, however. The significance of this difference is not entirely clear. Despite the same build numbers. the file sizes of the two builds are different. For those who are concerned, you will likely be able to crossgrade to the official release using the same technique as yesterday. We'll post details of this after some testing. The iPhone 2.0 Firmware provides a number of new features and also provides support for the iTunes App Store.

MacRumors to the rescue

I can't tell looking at my phone, but by downloading the "official" firmware and following the steps in the link above (repost: https://www.macrumors.com/2008/07/11/...-2-0-firmware/)

I feel a little more confident the new official firmware has overwritten the Thursday firmware.

Hope that helps.

Believe me...I know... I've spent 2 full days doing barely anything but iPhone restarts...

Wasn't that bad though - just had to survive the complete resync. The firmware update appeared (can't say for sure) to go faster/smoother than the Thursday firmware. I've given up setting up all my preferences/screens until I'm sure I don't have to load again for some reason...
