Hi,
Greetings

I am new to this forum and would like to know "How to update/ upgrade the pre installed applications like "Swipe" & "Google Navigation"".

We need to know more about your smartphone.

1. Is your phone rooted?
2. Swype (could also be doable with your phone): Click here.
3. For the other applications, i don't know about any update. Did you check it before, if there is an update available?
4. Don't (!) remove (maybe) systemrequired applications. Note: If you'd try it, do a full backup of your phone.
   The chance, that you can brick your phone, is very (not to say: extreme) high, if you do so.

Most of the default applications should update themselves, but if you're rooted you can use something like Root Uninstaller to delete the current version of an app and later install a newer one.

At your own risk, of course.
