What are the issues of upgrading a jailbroken iPhone 2G from 1.1.4 to 2.2?

[kunalashar]

I have a jailbroken 2G iPhone running firmware 1.1.4 with lots of downloaded applications, and everything is kosher.

I was thinking of upgrading the firmware to 2.2 (the latest). Research on the net revealed that users *seem* to have encountered a lot of issues with the 2.x firmware, including:
1. Hanging at the boot logo/screen
2. Repeatedly rebooting without ever going past the apple boot logo
3. Vanishing EDGE settings
4. Inability to get past the "Emergency Calls" screen
5. Limited/fewer number of free applications available on 2.2 than 1.1.4
6. iPhone hangs/locks up when sliding the "Slide to Unlock" slider

Are there any more known issues? What are the real risks of upgrading to the 2.2 firmware?

I'd like to leave well enough alone, but I'm tempted by some of the newer apps that have appeared on the iTunes AppStore, and I can't acces the AppStore unless I'm using firmware 2.2.

Any ideas?
TIA.

After some difficulty (and 2 retries), I managed to upgrade to 2.2.

Now, when accessing the internet over the wireless, the iPhone has become *SO SLOW*, that I'm tempted... nay... *sorely* tempted to fling it across the room, preferably at something unyielding, like a wall.

Any suggestions or tips on what the problem could be?

I have a 2g jailbroken iphone v1.1.4, trying to upgrade to v2.2 . But i am quite afraid of doing so, cause i just bought it, it came jailbroken already, and i would also like to know if its gonna brick or lock my phone. Kunalasharar, please help me upgrade mine too! Thanks

I initially tried jailbreaking with a semi-proven custom firmware file that was posted at http://www.megaupload.com/?d=h1ma9nov and at the http://www.modmyi.com/ forums.

That didn't work (meaning that the jailbroken phone had quite a few issues with the EDGE network, wifi, Cydia, etc.).

I then shifted to the regular fw file, followed by a QuickPwn. Most of the errors vanished, except for (1) the wifi problem (2) the refusal of the AppStore app to connect (???even over EDGE) and (3) failure of synchronization using Outlook (outlooksync kept crashing on my PC).

Another restore+jailbreak+unlock fixed all the errors except the wifi's infuriating slowness. Just one other computer was on the wireless, and it wasn't a bandwidth issue.

I did another jailbreak, and this time it refused to connect to my wireless ("Could not connect to <<wireless>>"). I had to reset the network settings, and now everything seems fine.

I'm keeping my fingers crossed.

(Nothing ever comes easy huh?)

My wifi problems turned out to be because of fw 2.2.

A post by a member on another forum mentioned that fw 2.2 has problems with wifi networks that use WEP encryption (apparently it's not even supported in fw 2.2).

I changed my wifi encryption to WPA2-PSK and viola! All the problems vanished. The wifi connectivity that had become shaky, unreliable and slow suddenly righted itself. And I didn't even have to reset my network connections, leave alone do another restore/jailbreak/unlock/reboot.

!!!

There is no reason to be using WEP nowadays. It provides no practical security.
