iPad says 4.3.5 but blob says 4.3.4

So you have 4.3.5 installed, and Cydia says you have blobs only for 4.3.4, right? (the top of the Cydia screen in Green when you start it?)

That is not an error. It is perfectly normal if you only recently jailbroke. You can only save blobs from Apple, and they only provide you with blobs for the current firmware when you ask. So, you were far too late for 4.3.3 probably. You first asked when 4.3.4 was out.

Blobs have nothing to do with the firmware installed, they are dependent on what Apple is handing out on the day you ask for them. That is why it is so important to save them away when they give them to you.

I'm afraid, based on the information you provided, you are only entitled to install 4.3.4 and 4.3.5 today, therefore you are pretty much stuck with 4.3.5 (no point in downgrading to 4.3.4, it is exactly the same tethered jailbreak as 4.3.5).

So, you either need to live with being tethered on your trip, or restore stock 4.3.5 and live without the jailbreak during your trip. Sorry.

 

Makes no odds. You are stuck with 4.3.5. Sorry.

 

Sorry, I obviously didn't pick up what it was you wanted information on in your original post.

Nothing will ever stop you from reinstalling the latest stock firmware unless your hosts file is not pointing at Apple. This probably changed in your situation because you used TinyUmbrella. But it is easy to correct.

To fix your problem it is important that you open TinyUmbrella, switch to the Advanced tab, and UNTICK the box which says "Set hosts to Cydia on exit".

Then you can exit TU, open iTunes, and press RESTORE. This will allow the 4.3.5 firmware to be reinstalled without a problem.

If you still get an iTunes error message, put your device into DFU mode and try the restore again. More info on that here - http://www.ipadforums.net/ipad-hacking/27489-dfu-mode-dummies.html

Hope the helps.
