Hi, recently I bought a jailbroken iPad. Can I update to the latest version without uninstall jailbreak?

NO. you will have to re-JB after the update.

No...update new / latest ios then jb the new / latest ios .

What happen after I update to the new iOS. All apps will be wipes just like a new iPad or all apps remain? Latest iOS is 6.1.2 is it?

yup..be sure to do a backup before u update or restore to latest firmware...
super important...

remember don't update on the air..
suggestion by evasi0n team if u wanna to jailbreak again..
just use iTunes restore and update method..

But my suggestion is stick to iOS 5.1.1 first... Nothing much difference just a new wallpaper, Siri , Do not disturb etc.
On iOS6.1.2 , my battery life decreases significantly.

after update u will have clean ios.. like new

Thanks for your reminder. I already backup my iPad in iTunes.

Thanks. Will stick to 5.1.1.

How to update the JB version to new iOS? Is it same as non JB iOS to latest iOS?

how to backup cracking version apps? Is it same like backup original apps with iTunes?

really... How about compare with 5.0.1 and 5.1.1 which one more battery saver?

Not sure about 5.0.1 since my stock ipad 3 come with 5.1.1
U using what device? iPhone 4? Only A4 processor can be down-gradable if I not wrong. So new device u don't have the choice.

Recently I download a app called 金山电池医生 (Battery Doctor)
iTunes Link HERE
My battery life boost significantly even on iOS6.1.2 , but it take very long time to fully charge my iPad 3 , about 12 hours (normally about 5~6 hours)

Last week when I restore + update to iOS 6.1.2, I did a backup but all my free apps + crack apps lost, left only photos and music. You can try a way, but not guarantee working. U use iFunBox to backup the ipa file. This method only works in crack apps, apps downloaded from iTunes not working if I not wrong cause I tried before. Then after u update then jailbreak then download appsync 6.0+ then install ipa using iFunBox.

Don't update directly from your device. Go download latest iTunes version, click "Restore and Update". If non-jailbreak can update to latest without restore, but if jailbreak update directly might cause problems (which I heard from other forum)

i m using ipad2
Ar u mean ifunbox can create iPa file from existing apps that don have iPa file backup?

Anyone with IOS 5 just lost their opportunity to update to IOS 6.1.2 as Apple has coming out with IOS 6.1.3 which currently can't be jailbreak using evasi0n. Sorry, you've missed the train ;-)

Stay a while with current iOS
The latest 613 still un-JB-ed yet

If you still insist, then its your call~
