[Q] Phone/Launcher keeps rebooting topic

First off all, I'm not sure if this question is answered else where.

I have my S2 almost since the day it came out in NL.

Today a problem occurred. After I boot my phone it keeps rebooting the launcher (not sure if that's the correct name). The phone it self stay's on, I don't go back to the Samsung logo or what else - just Android it self keeps rebooting.
I run Go Launcher Ex for a long time, never had problems with it.

I assume it's a memory problem.

Had a similar problem about a year ago, where my internal memory was stuffed. After removing some apps etc. my phone was just fine again. Problem today is I cant do anything. Connection with pc fails, because of the rebooting software. I'm not even fast enough to get to the Android settings.

Edit: I tried booting in Safe Mode. Which works, till it reboots into normal mode.. and keeps rebooting. And of course there's no time to get something done in safe mode.
- Phone get's really hot when this all happens. An other indication for a stuffed memory(card) I think?
- Removed the SD + SIM, no changes.

Thanks in advance,
