I just recently got an iPad running the iOS 4.2.1. I jailbroke it earlier today, not knowing that there were so many problems with it. I haven't experienced any of the problems on here and I haven't downloaded anything from cydia. I have, however, bought a few paid apps from the default App Store. How can I remove the jailbreak and keep all of my apps I previously had?

Do a restore with iTunes and it will remove the jailbreak. And it you already paid for the app then you don't have to pay for it if you download it after you restore. And iTunes will back it up anyway.

Thanks a lot. When I restore using itunes should I restore to factory settings or from last backup?

If you want to not have to download the apps on the iPad restore from a backup. But if you want a clean slate, restore to factory settings.

If I do a restore to factory settings, does that wipe out all evidence of a jailbreak? I.E., can Apple detect that it was jailbroken and refuse warranty service?

Apple cannot tell.

Cool, thanks for the info.

If I jailbroken my 4.2.1 and installed a few Cydia apps is it also safe to restore from backup (iTunes)? I hope so, but I am very confused now as many posts tell about SHSH keys which I do not have and cannot obtain for 4.2.1 anymore.

Can you confirm a more generic theis: One can do whatever like with iPad untill it works and iTunes can Restore backup on it. After restore all data is restored like bit copy of the whole filesystem.

I keep fingers crossed that it is true

You can restore whenever you want without any problems.

The only time you would need SHSH blobs is when installing an older firmware (such as 3.2) again,, but for restoring iTunes backups this is not nessessary.

Jail breaking doesn't mess up devices. It's only when u download and install something from cydia from which u did no research on that problems occur. I never had one issue jail breaking and done it several times since I got my iPad back in July. So it's kinda false to say there are problems associated with jail breaking. There are none. Only User Errors..lmao
If u wish to go back to restricted OEM access, just wipe clean and restore. U can still get ur apps back n apple would never be able to tell u jailbroke in the first place.
Jailbroken iPads run wayy better thn stock. With all the speed n usability tweaks, Jailbreak is the way to go.
Research 1st. Don't go jumping into the deep end without lookin and knowing how to swim. So for the record, there are no problems associated with jail breaking, only problems with what YOU did afterwards ;-) u can't go trying to install any and everything from cydia..lol
