Moved Dalvik to SD ages ago, just put in different SD. Problems ensue...

Title says it all. So when I realise my mistake, I put the SD card that was in before back. This card has had nothing done to it, just removed. When I turned it back on my home launcher is gone and so are almost all my apps. I reboot. Same. Over time, my app drawer is getting bigger with my apps but I'm getting low space warnings. I haven't had those for ages. Is it rebuilding the Dalvik and will be ok soon or is something bollocksed?

Help please.

 

Time has passed and things aren't good.

Constant low space message and so little space that my phone is sluggish as hell.

Market isn't installed either.

No idea what to do.

 

Yeah I still have my old card. I kinda know what I should have done. I'm usually pretty good with back-ups but as I wasn't planning on changing anything I didn't back up.

It's cool, I suppose I was ready for a new ROM anyway. I'm just looking for an easy option for plenty of app space, decent battery and AOSP. I don't suppose anyone wants to recommend one that'll be worth a look?
