Infinite-t, your explanation was good. But I have some questions about my trouble. I bought a i897 captivate 2 months ago from USA. I unlocked it. Hovewer, I cant use at&t applications. I also didnt like its navitagion because it didnt work without internet connection and its interface is not user friendly.
So I decided to root my phone. I have read many documents from xda and this site. There are many info that makes me confusing such as stock, jr7, bloat it, froyo, odin 1 click, cognition v2.1.2 etc.... I exactly dont know what they are used for.
I want to use all my phone's specialities and also have a nice navigation which doesnt need and internet connection. I download titanium backup and clockworldmod and I backup my phone with both of them.
Now Please advise me a way that I reach my aim easily and with least risk.
Well lets start from the top. Since you are saying that you purchased and unlocked a captivate from the US I am going to assume that you are not in the US and aren't using it on the US AT&T.
Both the att and Google navigation. Use your data connection for downloading map info since.the.maps are.not saved to internal memory. The only way around this would be find some app in the app store that includes a map pack that is saved to your phone memory so it doesn't use data to download map info.
Stock= as it was out of the box. No modifications.
Jh7= the first official update.for this phone pushed by Art.
Froyo= android 2.2 the next big software update for the android OS.
Odin 1click= a recovery program to restore your phone to factory via USB. Used when you r phone gets soft.bricked.
bloat: refers to the preinstalled att apps pre loaded on the phone.
Cognition is a custom ROM for the captivate. It replaces the stock OS and is basically bases on the stock OS but with many common modifications people do to their phones like the GPS tweeks, hiding and disabling the bloat, using a custom launcher, etc. I would not.recommend it to beginners.
I think you might not have access to ATTs apps if you aren't using the phone.on ATTs network.
So a few.things for a beginner to try:
Download launcherPro from the market. Its a very cool launcher that will replace the touchwiz launcher. It allows a lot more customization and is a lot quicker. It is also free. With it you can also use it to hide app icons in your app drawer for ones you don't use. Read the website for the app so you can learn how to use all the cool.features. I think you'll find you really. Like it.
