Hi there, do you have root access on your phone?

 

Okay.. I used 2 apps to do this..

1. Droidsail App2sd to move other apps thats been installed on phone by user..
2. Titanium Backup Pro (to move default internal apps)

But I'm not good in teaching so you might want to google for those on the net. Just be careful when trying to uninstall/move any system files with titanium backup..
Hope this helps

 

Even with root there is not much you can do, there is just not enough space on this device, unless you create more space like most of the rooted users do.
I mean you can make an ext partition on your sd card, use a custom kernel and use link2sd to transfer all your apps on the sd card.
I use cronmod script(link is in my signature below) instead of link2sd and i have about 500mb of internal space which is quite enough for all my apps.
