Most of the time we usually re-format our phone memory and even memory cards for a another clean install or just want a fresh new phone.
But the thing is, we install all our favorite symbian apps and themes again, one-by-one, and that makes a time consuming, isn’t it?
Now, i am going to share you a very handy freeware tool called AutoInstaller.
This tool will install all your favorite apps and themes automatically without any user interventions.
Run it then just wait for it to finish install all your favorite apps and themes.

How to use:
1. You need to copy all the applications and themes you want to install on
E:ThinkChangeC -or- E:ThinkChangeE
Create the folder if it doesn’t exists.
2. Open AutoInstaller application, press “Start Install“, it will automatically install all the files from that folder to your Phone Memory (Drive C) or into your MemoryCard (Drive E).
3. After the process is complete, there would be a summary telling you which files failed to install.
Noticed the C or E colored in red on step 1?
E:ThinkChangeC – if you want to install the apps or themes in your phone memory.
E:ThinkChangeE – if you want to install the apps or themes in your MemoryCard (MMC)

Thats all there is to it… Easy to use and less time consuming.
This is unsigned version so you need to sign it w/ your own certificate and keys or Hack your phone.
