Best remedy for unlocked 3g with slow iOS 4??

[AlertInTheUniverse]

Hi everyone,

I have been searching for the best way to fix my ridiculously slow iPhone 3g. I have been running iOS 4.0.2 basically since the jailbreak/unlock was possible, and since then have been waiting (like, with a burning --no, make that raging-- desire) for something better/wracking my brain to figure out what that something actually is.

It seems that I could upgrade to 4.2.1, but is that any better? I would like to be able to run apps requiring iOS 4, but I guess I'd be willing to give them up if that's the only (bearable) option. I am nervous to try this because it seems I would have to use the iPad solution, which seems to be irreversible if it ends up sucking. If I should upgrade to 4.2.1, what's the best way to jailbreak and unlock?

So, if 4.2 is no better, then I guess I would like to downgrade back to iOS 3.whenever-it-was-still-good. My baseband is 05.13.04, and the only backups I have are on iTunes and a blob from the current version. Can I downgrade? If so, then what, in terms of unlocking and jailbreaking?

Yes, I'm a bit of a noob, but please don't dumb it down for me! Any help would be great -- Thanks!!

I would advic u to downgrade. iOS 4 Is hardly bearable on a 3G and so 4.2.1 won't be any better..
Downgrade to 3.1.3 by following these steps
Download following things
1) 3.1.3 ipsw http://appldnld.apple.com.edgesuite....8_Restore.ipsw
2)Tinyumbrella. The Firmware Umbrella - TinyUmbrella
3)Spirit Spirit

After this:.
1) shift restore from iTunes using the 3.1.3 Ipsw.
2) u /might/ get a 1015 error .. If u get it use tinyumbrella exit recovery .
3) activate the phone using the official carrier sim.
4) run spirit.
5) download ultrasn0w from cydia.
Done !!

You can custom restore to a whited00r custom firmware which preloads iOS 4 features but keeps it on 3.1.3 firmware. I'm not sure if the iPad baseband is also preloaded into the custom firmware...

looks like whited00r doesn't change the baseband...

a couple of questions:

1. can i restore from my last backup?
2. can i activate with my original sim (AT&T) if i am out of the country? (i live in Germany)

[xtacy]

1) no . Higher firmware backups dont work on lower firmware..
2) yes.

[AlertInTheUniverse]

for #2... even if i have no signal? what do i need to do? it's been waiting for activation for a while now...

[AlertInTheUniverse]

it really doesn't seem to be activating. is this a signing problem?

also... somewhere along the way, my baseband has been upgraded to 5.14.02. does that mean i won't be able to unlock? now what??

[xtacy]

It's not possible that your baseband was updated if u followed what I said...
Also can u access teh springboard?

[AlertInTheUniverse]

Hrm, I'm not sure... I tried some other things last night when it wouldn't activate. So now my baseband is 5.14.02, in any case. Does this change things, or should I just try your steps again?

[xtacy]

Uh.. Can u access the homescreen? The icons and all?

[AlertInTheUniverse]

ah, yes... sorry, being a bit dense this morning.

[xtacy]

Then the phone is activated.. Don't know how u updated your baseband !!
You are on 3.1.3 right ?

[AlertInTheUniverse]

Every once in a while a message pops up that says it's waiting for activation, even when I'm on my homescreen.

I think the baseband thing probably happened when I tried to upgrade again because I forgot to backup my phone numbers. Now I am back to 3.1.3 --- do you still think everything should work?

[xtacy]

Yeah.. Hmm.. Check ya pm
