Can I rollback the OS on my Galaxy S2?
I gave in this morning and upgraded to Ice Cream Sandwich and I want Gingerbread back, loads of stuff doesn't work right now and I just don't like it, wish I hadn't bothered.

Yes, you can. How you do it is another topic all together. Google is your friend

I'm wondering if I just do a hard reset if it will restore it to how it left the factory.
My main issue is, now when I receive any emails to my phone with attachments the email simply says "null" and it doesn't show them

What email client are you using (i'm guessing it's not Gmail rather the Touchwiz client)? POP3 based? Is it up-to-date?
Was the ICS update official? OTA?
Best bet is to have a look on XDA Devs or Modaco; it's doable but if the baseband has changed (likely) then it's going to be a PITA.
However i'd do a factory reset first, go through adding your email accounts again and see if that sorts it before peeing around with downgrading.
I'd also recommend trying the K9 email client (from the Play store), it's pretty decent are certainly better than the Touchwiz client.

Hard reset restores to factory settings.

It'll reset the settings but it won't downgrade the firmware back to 2.3.

I did it and it was on 2.3, assuming the phone was already on 2.3 and never upgraded then!

That's not a bad shout, I'll try a different client. I just generally like to use the shiz that's already installed.

Deffo not? I don't mean in the setting where you click on factory restore, I mean punching the code in that makes the screen flash black and red and basically reinstalls the system to how it left the factory.
EDIT: *2767*3855# This one, I dare someone to type it in.

yeah that doesnt take it back to gingerbread, I have tried this when on the phone with htc to see if it solved my issues that i have had since the ics update, 3 software updates since and i still have issues i have just given up and learnt to live with it.
edit: how to guide here http://cs-pages.blogspot.fr/2012/04/how-to-downgrade-android-os-simple.html

If you do a Google there are a few forum threads about users having problems with the updated Touchwiz email client (if that is what you're using).
As said, i would first do a factory reset and see where that gets you. It might just be a bodged setting/setup. Failing that, look into rooting the phone, remove Samsung's Touchwiz email client and replace it with the stock ICS email client (look on XDA as there is probably a guide for this). Or use a different email client like K9.
Do you have these issues using the GMail app? Or is it just isolated to the Touchwiz client?

flash the RRU rom (completely stock rom from Samsung) for gingerbread, will wipe everything on the phone. XDA developers is your friend for the rom and how to flash it.

Good shout on K9 Dom, like it and solves my email issue. ONLY problem for me is that the widget icons you can have that will show the number of unread on the home screen will only do it per inbox, not collectively over several like the standard built in email.
