Thanks for the reply. Although in my case new apps do not install to SD by default, I could move a couple of apps that I couldn't before such as System Panel, HTC Sync and Comic Reader Mobi thus gaining around 6 MB, plus all the widgets (of course I didn't touch them and let them where they were). It wasn't possible to move Facebook though as mentioned by chrisrosevilla.
Rooting+A2SD is indeed better to gain advantage of all the partitions but till now I didn't have the nerve and I also didn't want to lose the looks of HTC Sense. I will go at the end with a ROM that offers Sense on top, but till then I will compensate with this trick.
