What does 4.2.1+ mean?

the + sign?
does it mean every firmware version after 4.2?
Coz i did select "make my life easier"
shouldn't cydia download every SHSH for me ?

To get TinyUmbrella, a simple google search would definitely lead you to it's official blog, with download links obviously there. It's not hard to get it without asking from fellow members here, isn't it?

To save SHSH blobs, connect your iDevice and run TinyUmbrella, then select your device and hit Save SHSH. This will allow TU to connect to Apple server and retrieve all currently available SHSH for your device.
For example, currently Apple is signing for iOS4.3.5, iOS5+ (all beta versions), so in the end you'll get the SHSH for iOS4.3.3 and iOS5+. For versions which Apple had already stopped signing, you WILL NOT GET THEIR SHSH.

But there may not be 100% case. One exception is that you had jailbroken your iDevice before, and Cydia had automatically saved SHSH blobs for you without your awareness.
For example, you jailbroke your device on iOS4.1, once open Cydia and it save your iOS4.1 SHSH blob automatically on it's server. Some time later, Apple announce iOS4.x, you once again open Cydia during this time, Cydia then helped you save the new version iOS SHSH automatically. All the saved SHSH blobs on Cydia server can be found like this:

If this is the case for your iDevice, you can:
1) Connect your device to PC and run TinyUmbrella.
2) In TU, go to Advanced tab, check on the option "Request SHSH From Cydia".
3) Hit Save SHSH and all your SHSH on Cydia server should be saved on your local drive.

may i know if i use another computer to do "Just tethered right now", is it gonna work? or i must use the computer previously i used for jailbreaking it?

since, i am helping my friend to jailbreak his 4.3.5, i am gonna give him back. in case, it reboots, i want to know how.

thanks!

Can be done on any computer

can be done on any computer as long as i have Redsnow 0.9.8.4b file and 4.3.4 file?

that means if i bring along a pendrive having both of these files, i can do tether on any computer(PC, not Mac)?

thanks!

Yes. Just make sure the required drivers are installed on the PC (which will be automatically installed with iTunes).

Or you can get them here (I extracted from iTunes installer):
Apple Application Support
Apple Mobile Device Support

drivers? any computer doesn't have drivers?

what drivers do we need?

i'm quite confused. i didnt install any driver before i jailbreak.

Added on September 27, 2011, 12:39 amu meant i just need to install iTunes instead of looking for drivers!

i need to have either the required drivers' installers or iTunes. right?

Yes, as long as you'd installed iTunes, then you don't need to find any drivers. They are installed together with iTunes.
I just give the link for the drivers in case you don't want to install iTunes

I don't think so. I think you only have up to 4.2.1. As for the plus signs I'm not sure.

What you can do is download the latest tinyumbrella and set "check SHSH from Cydia" in the Advance Tab. It will retrieve ALL SHSH that Cydia has saved for your iPhone locally. If it has saved the 4.3.3 SHSH, then TU will retrieve it for you. If it did not for one reason or another, then you are out of luck.

wow wow thansk sifu. ya here many sifu and there are very helpful to me (im not much know all abt this) so i also will carefully to do this eheheheh

thanks a lot sifu here

bro...what font is that..??

how can i do it like you do?

I have never done a tethered JB before, just for confirmation sake and info sharing can someone confirm that you will need to reboot tethered

1. If your battery runs out
2. If you reboot your iPhone (i.e installing some tweak in Cydia which requires a reboot)

Can somebody confirm that Respringing does not require you to boot tethered?

respring does not require to boot. confirmed.
unless, when ur respringing, ur phone crash(sometimes happens to me)
then you will have to boot tethered with ur pc.

Thanks for the info .... then it's not so bad to do a tethered JB coz a lot of the time it's the re-springing that you do most often. Reboots only if you install some of the Cydia tweaks.

Haha nice font isn't it? I like it very much

Just search for BytaFont in Cydia store, download and install it.
After that, search for font QarmicSans in BytaFont, apply it and respring and there you go

*Remember to backup your original font

Never heard of this before .... this is weird. Did you encrypt the backup file?

no, before he give me the iphone.. he use passcode for the iphone.. and then i ask him to off it. and he off the passcode.. maybe that reason i can't restore back

Don't think the phone passcode got anything to do with itunes right? On top of that you have already downgrade from the previous version.
